The Gang gets Freudian as they step into the therapist's office to work through their mountain of issues. But when Dennis thinks he has everyone figured out, the shrink turns the tables on him and exposes the insanity in his unique brand of pop psychology. Dennis' psychology is exposed as abnormal indeed.

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. While an unwritten rule of the bar gets the rest of the gang caught up in a case of mistaken identity.
