In season twelve, Mac, Dennis, Charlie, Dee and Frank tackle all new adventures that include going to a waterpark, dealing with a Wolf Cola PR nightmare, and actually spending a whole day tending bar!

The Boggs plane challenge, “group dating,” and all-timer Charlie Work lead into spy games, a culty fitness craze, and a rigged turn on “Family Fight.”

Dee hits “rock bottom,” gun fever reignites, the bar begs for an award, and the 100th episode plays out via convenience-store fantasies. Charlie gets “smart,” the Gang funds Lethal Weapon 6, and everyone tries to squash decades of beef at Thanksgiving.

Pop-Pop’s “final solution,” recycling old scams, Maureen’s feral-cat wedding massacre, therapy day, and a courtroom cereal fight wrap a tight ten.
