Mac and Dennis pursue the ultimate high of hunting another man by stalking Rickety Cricket, while Dee and Charlie become obsessed with eating human flesh after they come to believe Frank has fed some of it to them.

While Mac, Dennis, and Charlie use their classic setup to sell gallons of gasoline door to door, Frank subjects Dee to a series of torture and mind games when he suspects that Dee is trying to kill him while the two plot to steal their inheritance from Bruce Mathis.

After buying a billboard, Frank subjects Dennis to a series of humiliating tests in a competition to get on the billboard, while Mac tries to find female subjects willing to go through his own version of a reality show, of sorts.

Charlie manipulates Mac and Dennis when he accuses the two of them with sleeping with the coffee shop waitress.

Frank and Charlie find someone has pooped in their bed, leading Mac and Dennis to join them as they attempt to find the culprit.

The gang kidnaps the writer of a review claiming that Paddy's is the worst bar in Philadelphia and tries to force him to change his mind. But things get worse when Dennis and Dee accidentally kidnap the writer's neighbor.

While Frank and Mac come up with ways to spice up Dennis' erotic memoir, Dee finds that spending time in Charlie's shoes is way more difficult than it seems, and vice-versa.

After Dee suffers a heart attack, she and Dennis try a healthier lifestyle. Charlie and Mac join the corporate work force to get health insurance.

In order to get Paddy's recognized by the city as a historical landmark, Mac, Dennis, and Charlie flash back to 1776 to tell the tale of the Paddy's crew's involvement in the cracking of the Liberty Bell.

While trying to make their own dreams come true, the gang decides to pay it forward to an unlucky family living in the city only to have their plans backfire on them.
