- Official synopsis
This season, stay tuned to see the Gang go to therapy, hunt for Nazi treasure and try to undermine Philly’s toughest union – the trashmen! Charlie and Dee find love, Frank re-enters the business world, and Dee blurs the lines between the real and virtual worlds when she falls into an obsession with computer games. Get ready for even more disagreements, disunion and divisiveness as the Gang tries once again to scheme their way to happiness!

("Pop-Pop: The Final Solution") With the South Philly waste management workers on strike, Frank concocts a plan to get the contract to collect the city's trash; The Gang realize that they've ran out of original money-making schemes. ("The Gang Recycles Their Trash") In a police department, The Gang explains why they've crashed on Maureen and Liam's wedding, and start to fight all invited "zombies" - Halloween, baby! ("The Maureen Ponderosa Wedding Massacre") Charlie and Dee find a romantic connection with two members of one of Philly's wealthiest families; the rest of The Gang tries to get their piece of the "high life" action. ("Charlie and Dee Find Love") The Gang gets Freudian in the therapist's office, who finds Dennis' psychology to be abnormal. ("The Gang Gets Analyzed") As Charlie's mom battles the lung cancer, Mac, Charlie and Dennis are holding a "Beef & Beer & Jesus" fundraiser at Paddy's; Frank and Dee are in the quest for buried treasure. ("Charlie's Mom Has Cancer") With Charlie under his wing, Frank cleans up so he can get his hands dirty and help out his old company with one last big merger; Dee, Dennis and Mac are tries to get some benefits out of Frank's "new" status. ("Frank's Back in Business")
The whole Gang falls into an obsession with computer games. ("Charlie Rules the World") The whole Gang take a night out of Paddy's and tries to put themselves on airs at Guigino's Italian Restaurant.
("The Gang Dines Out") When Frank accidentally hits Dennis' car, it's a real tragedy: Dennis spills his cereal all over himself. (Because it's totally normal to eat cereal while driving.)

- This is the first season in HD with all The Gang members in "standard condition"
(no one is getting pregnant, and no one is cultivating mass).
- Shootings of the 8th Season were officially completed on October 5, 2012 - less than a week until the start of broadcast. [Their last filming location - Hilton Hotel on 168 S. Los Robles Ave, Pasadena.]
- This is the first season where no episodes were filmed in Philadelphia, PA.
- The premiere date was originally pushed to October because of the Kaitlin Olson's pregnancy - she gave birth to her second son on April 5, and they usually started studio shootings in April. [Rob McElhenney: "Kaitlin was pregnant with Leo. Although she gave birth in April, we still wanted to have enough time that we could both spend not sleeping and being up three, four times a night. And being able to focus on him and not being worried about anything else. And that was a key factor. And then Charlie was doing this movie, so he was in Canada for a while, and Danny was doing a show in the West End of London".]
- A 10-episodes season allows the actors time for the outside work and gives them some time to raise their children, but production of the show is still take seven or eight months out of a year.
- Season Two consisted of 10 episodes as well.
- This season broke the record for number of episodes written by all three executive producers -
- Here comes a photo from 8th Season premiere screening party!
- The series' new crew member, director Richie Keen, did five episodes for Season 8. Another new member, director Todd Biermann, did only one episode.
- Many episodes of this season call back to previous episodes -- in fact, the episode "The Gang Recycles Their Trash" is pretty much entirely built around callbacks to previous episodes. Practically every episode has a callback to something that happened previously, however.
