Early History[edit | edit source]
Mac and Dennis have known each other since high school. According to Dennis' recollections of high school, Mac was a drug dealer with no friends while Dennis was immensely popular ("Underage Drinking: A National Concern"). However, we later learn that Dennis was not as popular as he claims to have been, and spent all of high school hanging out under the bleachers and behind dumpsters with Mac and Charlie ("The High School Reunion, Part 2: The Gang's Revenge"). Even though they were friends, Mac slept with Dennis' prom date and covered it up by telling Dennis that Tim Murphy did instead. Dennis doesn't find out the truth until years later ("The High School Reunion, Part 2: The Gang's Revenge"). By season four, Dennis and Mac have been living together for approximately ten years, meaning that they moved in together sometime in 1998 ("Mac and Charlie Die (Part 1)"). At some point after Dennis's graduation from the University of Pennsylvania, Dennis and Mac bought Paddy's Pub along with Charlie. The two of them convinced Charlie to trade his shares of the bar to them for Garbage Pail Kids card and half a sandwich, and are thus currently the only shareholders ("The Gang Sells Out").
Season One[edit | edit source]
Initially, Mac and Dennis are shown to have a rather antagonistic relationship. Even though they are best friends, this is consistent through all the seasons of the show, but especially in the first season. Mac tries to put Dennis in harm's way by getting him blackout drunk as part of a scheme to end Dennis's insistence upon running a gay bar ("The Gang Gets Racist"). He and Dennis also compete for a woman's affections when she comes to pick up her dead grandfather from their bar, with Dennis eventually sleeping with the woman and infuriating Mac enough to tell Dennis that the Reynolds' own grandfather was a Nazi ("The Gang Finds A Dead Guy"). Their friendship is more positively portrayed when, along with Charlie, they buy a gun together and become obsessed with it ("Gun Fever").
Season Two[edit | edit source]
Mac sleeps with Dennis's mom, an experience which he describes as "special and magical." Dennis punches him in the face for it and attempts to get revenge on him by sleeping with Mac's mom, but the two of them are later seen drinking together at Paddy's and appear to have reconciled ("Mac Bangs Dennis' Mom"). When Dennis and Mac coerce Charlie into joining an underground fight club and Charlie bails on them at the last minute, Mac steps in to fight in his place, and later discovers that Dennis had so little faith in his ability that he bet all his money on the other fighter to win ("Hundred Dollar Baby"). Their competitive streak continues while coaching opposing basketball teams as part of required community service ("The Gang Gives Back"), and also when Mac runs a smear campaign against Dennis when he runs for comptroller ("The Gang Runs For Office"). Together, they decide to make Paddy's Pub an "anything-goes bar," until the invasive presence of the incestuous McPoyles and Frank's gambling friends persuades them otherwise ("Charlie Goes America All Over Everybody's Ass").
Season Three[edit | edit source]
This season contains some of the earliest hints of homoeroticism that are prevalent throughout Mac and Dennis's relationship. When Dennis's mom dies, Mac, Dennis, and Charlie throw a party in Dennis's newly inherited mansion. To do this, they try to recruit partygoers with posters that end up shaped like penises, and Mac and Dennis in particular are fixated on finding attractive men to attend their party ("Dennis and Dee's Mom Is Dead"). When the gang is held hostage by the McPoyles, Mac abruptly confesses to Dennis that he loves him. The confession goes unreciprocated and neither of them make any mention of it again ("The Gang Gets Held Hostage"). Dee points out that Dennis is "the only person Mac would listen to" ("Dennis Looks like a Sex Offender").
When Mac, Charlie, and Frank decide to start a band, Mac enlists Dennis to replace Charlie after hearing Charlie perform a disturbing song about rape. However, he changes his mind after witnessing Dennis's spandex-clad, glam-rock-inspired performance style, and kicks Dennis out of the band as well ("Sweet Dee's Dating a Retarded Person"). Dennis, along with the rest of the gang, briefly suspects Mac of leading a double life as a serial killer, but appears to have no moral objection to this, and even gets excited when he and Dee try to get into the serial killer mindset themselves ("Mac Is A Serial Killer"). After witnessing how Frank has brainwashed Dennis into prostitution and endangered them all by almost sleeping with a mob boss's wife, Mac slaps Dennis around until Dennis starts thinking for himself again ("The Gang Gets Whacked (Part 2)"). When the bar holds a dance contest, Mac challenges Dennis to a dance competition because he says he is tired of Dennis not appreciating him, but loses after performing a series of dance moves that includes miming the act of fellatio on Dennis ("The Gang Dances Their Asses Off").
Season Four[edit | edit source]
Mac and Dennis team up to hunt Rickety Cricket across the city for fun. The two make repeated references to teabagging Cricket, and before the hunt is over they perform variations of this act upon one another. Frank expresses how he "doesn't understand [their] generation" based on the fact that Mac and Dennis keep touching each other in ways that he deems inappropriate ("Mac and Dennis: Manhunters"). The gang holds a modeling contest and Dennis wishes to be one of the hopefuls, but is discouraged by Mac, who insists that while Dennis used to be "a stallion," he is no longer in his physical prime, and is no competition for the hordes of "beefcakes" that he is up against ("America's Next Top Paddy's Billboard Model Contest").
This season begins to hint at the strength of Mac and Dennis's codependence, particularly in the episode "Mac's Banging the Waitress". When Dennis overhears Mac and Charlie describe themselves as best friends, he quickly grows jealous and tries to turn Mac and Charlie against each other, even convincing a drunk Charlie to get in bed with him. Mac admits that he and Dennis have a bond much stronger than his bond with Charlie, describing them as "blood brothers." Privately, Dennis and Charlie agree that Mac is probably gay, speculating that he's in love with both of them and that his Project Badass videos are a way to get their attention.
When Mac and Charlie fake their deaths to hide from Mac's dad, Dennis realizes they're still alive almost immediately; however, angry that his friends didn't include him in their suicide pact, he taunts Mac by throwing out all his possessions and getting a brief replacement roommate ("Mac and Charlie Die (Part 1)"). After Mac's dad flees the country and Dennis forgives Mac and Charlie, Mac moves back into their apartment ("Mac and Charlie Die (Part 2)"). In order to add truth to Dennis's largely fabricated memoir, Mac gives Dennis nailgun stigmatas and, intending to drop him off in front of an asylum, accidentally leaves him for dead at an abandoned warehouse ("Dennis Reynolds: An Erotic Life"). When Charlie comes to the gang with his musical, The Nightman Cometh, Mac and Dennis switch the roles Charlie intended for them, with Mac playing the Nightman and Dennis playing the Dayman. They spend their rehearsal arguing over how to make the "rape scene" in the show as tasteful as possible, deciding to cover themselves with a blanket while Mac dry-humps Dennis. Although neither of them find anything homoerotic about this in the rehearsal, Dennis calls Mac out on getting an erection during the actual performance ("The Nightman Cometh").
Season Five[edit | edit source]
By this point in the show, Mac and Dennis's friendship and partnership is the fulcrum of many of the gang's schemes. They pretend to be realtors in order to sell Frank's house, creating personas "Hugh Honey" and "Vic Vinegar" for themselves, and develop these characters into a rich homosexual couple with explicit detail about who is the top and who is the bottom ("The Gang Exploits The Mortgage Crisis"). The two of them discover their inability to run the bar by themselves when they fire the rest of the gang and end up losing an inordinate amount of money ("The Great Recession"). In a rare moment of kindness, they work together to get Charlie a date after they find out that the Waitress is engaged, but their ever-present need to one-up each other is part of what ultimately foils the plan ("The Waitress Is Getting Married"). Recounting the events of the day of the 2008 World Series in court, Dennis mocks Mac for his crush on Chase Utley, and the two engage in a pushup competition whose winner is ambiguous ("The World Series Defense"). Together with Charlie they create short-lived wrestling team Birds of War ("The Gang Wrestles For The Troops"). After hearing Charlie's pitch for kitten mittens, Mac and Dennis conceptualize a number of their own ideas for bar merchandise, including dick towels, erotic pens, and alcohol-filled shotguns ("Paddy's Pub: Home of the Original Kitten Mittens").
The episode "Mac and Dennis Break Up" is entirely focused on their attachment to one another, and what happens when the two of them are separated. We learn that Mac and Dennis never go more than an hour without checking in, that they have a movie night every Tuesday (during which they typically watch Predator), and that they think of themselves as a "dynamic duo." Dee calls them out on acting like an "old married couple" and describes their relationship as "pathetic," which unsettles Dennis enough that he convinces Mac to move out. However, they spend the entire episode obsessing over each other and trying to use their friends as replacements, eventually irritating Dee enough into reuiniting them by secretly setting them up on a date and reassuring them that "it's perfectly natural for two grown men to need each other this badly."
When Dennis outlines his sick "system" for seducing women to rest of the gang, we learn that Mac plays a pivotal role in it; later, Dennis discovers that Mac has been sleeping with all the women Dennis sleeps with once Dennis decides he's done with them, something Mac describes as "swimming in your wake," and that Mac is not just his wingman but also his dedicated follower ("The D.E.N.N.I.S. System"). When Mac and Charlie attempt to pitch a movie idea to M. Night Shyamalan and run their ideas by Dennis, Dennis acts disinterested, but eventually reveals that they had his rapt attention and he was secretly developing a full screenplay out of their story the entire time ("Mac and Charlie Write a Movie").
Season Six[edit | edit source]
The season opens with Mac having a crisis: his ex-girlfriend Carmen is "gay married" to her husband, which Mac believes is a sin. During Mac's mission to eradicate gay marriage, Dennis is inspired to marry his high school sweetheart Maureen Ponderosa, and effectively uses her to replace Mac, once again kicking Mac out of their apartment and taking Mac off their cell phone's family plan ("Mac Fights Gay Marriage"). Mac becomes convinced, however briefly, that "anyone should be able to get married," possibly because being married to Dennis would have legally protected him from being thrown out and cut off by Dennis as quickly as he was. Dennis and Maureen's relationship quickly unravels, and when Dennis comes home with Mac after a night of going out drinking, Maureen tells Dennis, "I want you and your boy toy out of this house." Mac eventually convinces Dennis to go through with divorcing Maureen, which leaves Dennis saddled with Maureen's enormous debt ("Dennis Gets Divorced").
When Mac believes that Dennis intends to use their newly acquired boat to rape women, he becomes extremely uncomfortable, and tries to convince Dennis that his methods of "seduction" via what Dennis calls "the implication" are actually violent and dangerous; eventually Dennis convinces Mac to follow his lead, and the two of them lure a pair women back to their boat only to find that Dee, Charlie and Frank have burned it down ("The Gang Buys A Boat"). Dennis establishes his belief that he and Dee are higher-class than Mac and Charlie, something Mac is insecure about ("Mac and Charlie: White Trash"). Dennis briefly fears that he was complicit in killing Mac's dog, but Mac doesn't worry at all and the dog is revealed to be alive and well ("Mac's Mom Burns Her House Down"). Dennis, along with Charlie and Frank, suspects Mac of having drunkenly had sex with with Dee at the Halloween party, until Mac recounts that he had sex with Margaret McPoyle instead, and the McPoyle brothers reveal that Dennis is the most likely one to have slept with Dee that night ("Who Got Dee Pregnant?").
Mac and Dennis both try to reenlist Schmitty into the gang, even kicking Charlie out after Charlie gives them the ultimatum "it's me or him," but Schmitty is uncomfortable with how codependent they are, commenting on how it's weird that Dennis orders food for everyone just because he claims to have "the most refined palate," how creepy their rituals for re-initiation are, and how they don't have to take their friendship so seriously, which deeply rattles and angers Mac and Dennis enough to get rid of Schmitty and come crawling back to Charlie ("The Gang Gets A New Member").
Their mutual love for eighties movies, as well as their different views on the use of blackface, are showcased in their homemade movie Lethal Weapon 5, in which Frank and Charlie are supporting actors ("Dee Reynolds: Shaping America's Youth"). When Dennis and Charlie pretend to be Mac and Frank at the animal rights charity event in Atlantic City, Dennis gets to play catch with Chase Utley, something Mac has always wanted to do, and taunts Mac by drunkenly sending him a picture of himself and Utley ("The Gang Gets Stranded In The Woods"). When the gang thinks that Dee is keeping her baby and worry that they'll be stuck with all the responsibility of caring for it, Dennis actually gets excited about raising the baby with Mac and Charlie in a "Three Men and a Baby-type-situation" ("Dee Gives Birth").
Season Seven[edit | edit source]
Dennis seems concerned about Mac's weight gain this season. He insults Mac's weight several times throughout in different episodes, seemingly in an effort to shame him into slimming back down. At one point, he tells Dee, "Somebody's got to take care of Mac, and that's gonna be me" ("Frank's Pretty Woman").
Eventually he takes matters into his own hands. It's later revealed that he secretly gave Mac "size pills" to lose weight ("The Gang Gets Analyzed"). Dennis also mentions that Mac's constant wheezing and sleep apnea were irritating to him, despite ‘supposedly’ sleeping on opposite ends of the apartment.
It's revealed that Mac not only watches Dennis's sex tapes, but he also tries to watch him having sex in real life. He's seen Dennis have sex in the secret bunker beneath the bar before ("The Storm of the Century"). He complains that Dennis takes too long talking to women before sleeping with them, to which Dennis replies that that's because Mac continually barges into the room trying to see them having sex and that makes him have to start seducing them all over again ("Thunder Gun Express").
Season Eight[edit | edit source]
In the second episode of this season, while Dennis, Mac and Charlie are discussing whether they should begin selling gas door-to-door again, Mac goes in to kiss Dennis. Though he is unsuccessful and strolls off as if nothing has happened, it does not go unnoticed by both Dennis and Charlie ("The Gang Recycles Their Trash").
Dennis gives an impromptu speech about Mac in front of everyone at Gugino's, calling Mac his "hero" and "the wind beneath [his] wings." ("The Gang Dines Out")
Season Nine[edit | edit source]
While trying to catch a rat, Dennis argues that "seducing" the vermin is the best way to corner it, then turns on the song "You're The Inspiration" by Chicago, and he and Mac sway towards each other, with Mac eventually leaning in towards Dennis before Dee interrupts. ("Flowers For Charlie")
Season Ten[edit | edit source]
They get Dee distracted so they can take turns masturbating in her apartment, and didn't want Charlie to get involved. ("The Gang Spies Like U.S.")
Dennis devises a cult centered mainly around all of Mac's bodily insecurities in an elaborate but effective ploy to get Mac to stop eating his Thin Mints. He describes Mac as being "all annoying and shit", agreeing with Frank that Mac is the worst. When he finds Mac ditching an Ass-Kickers meeting eating his Thin Mints again, he tells Mac he is flabby and disappointing, having been "so much sexier before." He bought into the Ass-Kickers and claimed the final order was to light themselves on fire; it is unclear if he intended to let Mac (and Charlie, who was also in the cult) burn himself as well. ("Ass Kickers United: Mac and Charlie Join a Cult")
Season Eleven[edit | edit source]
Mac and Dennis move to the suburbs and attempt to live there for a month. This turns sour when they realize they are meant for city life– Dennis resents the neighbors and the long commute to work, while Mac resents staying home and cooking and cleaning for Dennis. In an emotional outburst over dinner, Mac tells Dennis, "Everything I do, I do for you!" Dennis, fire poker in hand with intent to bludgeon their neighbor Wally, rabidly snarls at Mac that he hates him and never told Mac he heard the fire alarm chirp that drove him to madness. ("Mac and Dennis Move To The Suburbs")
Mac approaches Frank about Dennis, saying, "Do you think Dennis hates me? I just want him to think I'm cool," and "I put so much of my heart and soul into our relationship." ("Being Frank")
Season Twelve[edit | edit source]
Mac and Dennis spend most of this season still sharing a bed with Dee in her apartment ("PTSDee"). Dennis is very encouraging towards Mac coming out and accepting himself in "Hero or Hate Crime?", reassuring him that he will feel better after doing so. However, Dennis also says that he still hates him, whether or not he is out of the closet. The rest of the gang agrees with Dennis that Mac is terrible.
After Mac comes out his crush on Dennis becomes a bit more pronounced. The first instance of this occurs when Mac has a dream where Dennis kisses him after he walks in on him practicing his stripper routine, something Frank refers to as "erotic nightmares" ("PTSDee"). In The Gang Tends Bar Mac expresses concern to Charlie that he believes Dennis is less comfortable around him now that he's out of the closet. Later in the same episode there is a heartwarming moment between Mac and Dennis when the former presents the latter with a Valentine's Day present, an RPG.
In the finale ("Dennis' Double Life") it is discovered that Dennis has a child. Mac suggests that he and Dennis act as a couple to try and convince Mandy, the child's mother, that Dennis cannot be a part of his son's life. It is obvious throughout the episode that Mac is a lot more interested in the fake couple scheme than Dennis is. In the same episode it is revealed that Mac had been refurbishing his and Dennis' apartment for some time, after winning a bet over who got to do so. He recreated the apartment to look exactly as it had when he and Dennis used to live there, except for one detail - with only one bedroom this time (Mac turned his old bedroom into a "home gym" with the Asspounder 4000). He claims that this detail was to accommodate for the living situation they had gotten so used to at Dee's, clearly expecting him and Dennis to continue to share a bed. When Dennis tells Mac he is going to sleep on the sofa instead, Mac assumes that this means that they would be sharing the sofa. Dennis ends up sleeping alone on the floor in the "home gym".
The twelfth season ends on a cliffhanger with Dennis leaving (possibly for good) for North Dakota to spend time with his son. The gang blows up his Range Rover in tribute.
Season Thirteen[edit | edit source]
When Dennis is gone, Mac gets a sex doll custom made to look exactly like Dennis in attempt to use something Dennis-shaped to fill his hole, to which the gang comments that "he definitely emptied his load in it". The incident later progressed to a sex doll orgy involving Mac, Frank and Charlie ("The Gang Makes Paddy's Great Again").
In Dennis' sexual harassment seminar, he tells Mac to stop touching and kissing him, as "it is never going to happen, not willingly". For the closing of the seminar, however, Dennis says he is teaching them to "be careful so they don't get accused", not to stop harassing people ("Time's Up for the Gang"). Mac nominates Dennis as the leader of the gang because he is "the smartest person he's ever met", while Dennis asserts his dominance on Mac by not allowing him to sit down, and later scratches him in the face again. It's also revealed in this season that there is a bed in Mac's room again, implying the closure of the sharing-the-bed discussion ("The Gang Escapes").
In Mac's reality, he and Dennis ran off to North Dakota together hand in hand. In Dennis' reality, the two are not roommates. He later admits that he does not want to be roommates with Mac because the latter "spends three hours a day on a dildo bike" ("The Gang Does a Clip Show").
Season Fourteen[edit | edit source]
Mac and Dennis plan a meet-cute scheme to AirBnB their apartment in order to attract women. Dennis shows little interest in the scheme, stating that he does not want to participate anymore and that it seems desperate from his end. Dennis decides he does not want to be personally involved in the scheme anymore, but agrees to help Mac ("The Gang Gets Romantic").
When there is a miscommunication involving Charlie outshining Mac in a plan, Mac becomes overeager to please Dennis. Dennis calls Mac desperate, stating that Mac seems "off his game." When Dennis is forced by Dee to remove his makeup, Mac is reassuring with kind words, reminding Dennis that he is still the Golden God, though clearly put off behind his back. ("Dee Day").
When Frank chokes on an appetizer, Dennis becomes concerned that Mac did not act in order to save Frank's life, coming to the conclusion that he cannot depend on Mac to keep him safe. Mac attempts to show Dennis that he can depend on him, but forgets the list of foods Dennis cannot eat, drops him when he carries him, and fails to keep track of weather conditions - furthering Dennis' lack of faith in Mac.
When Mac worries that Dennis will not be able to depend on him, he blends up soda and pizza into workout shakes in order to keep Dennis dependent on him, and almost gives in to a plan concocted by Dee to actually poison Dennis for real in order to gain his favor by saving his life. However, when presented with the opportunity to go through with the plan, Mac comes clean about the plan to Dennis. This further disappoints Dennis with the fact that Mac cannot think for himself. When Dee drinks the poison herself, Dennis asks Mac to save her. Mac refuses, deciding to make his own choice, and standing up to Dennis ("The Gang Chokes").
Dennis becomes angry with Mac when due to a misunderstanding with a texting chain, Dennis misses a zoo exhibit that he was excited to see. Dennis confronts Mac in the bathroom at the zoo, and Mac attempts to make it up to Dennis by telling him about a second showing of the exhibit (a live lion feeding). In a moment of sexual tension, Dennis lets Mac know he is pleased, but unleashes a thinly veiled threat that if he misses the second exhibit, he will "feed [Mac] to the lions himself", peeing on Mac's leg to assert dominance. When it turns out the exhibit is not what Mac thought, Dennis becomes angry and storms off. However, the two encounter each other in the Meerkat exhibit at the end of the episode, and share a lingering glance, in which Dennis sees that Mac is sorry. Dennis tells Mac that he is appreciative of the apology, and laughs at a text Mac sends at the very end ("The Gang Texts").
Dennis becomes frustrated with Mac's religious beliefs, and the two heavily debate the involvement of religion in climate change ("The Gang Solves Global Warming").
In laser tag, Dennis withholds compliments and "love" from Mac in order to obtain the best performance he can out of Mac in laser tag. However, the insults do not have the same bite that they did in prior seasons; this could be mercy on Dennis' end or simply proof of Mac's fragility ("Waiting for Big Mo").
