Season Summary[]
The Gang's schemes get even crazier this season: reselling gasoline door to door, getting healthy and scamming to get health insurance, and having the bar declared a historical landmark. They also kidnap a newspaper critic who writes a negative review of Paddy's.
Luther comes up for parole, so Charlie and Mac fake their deaths to avoid his vengeance.
Charlie continues to stalk the Waitress: he attempts to find out who is banging her, and then writes a musical and invites her to attend.
Greed gets the better of them, as they also attempt to prevent Bruce Mathis from donating Barbara Reynolds' assets to a Muslim cultural center.
