Dee dates a famous local rapper and it could turn out to be true love, even though he might be mentally challenged. In any event, his success inspires Mac, Dennis, Charlie and Frank to start their own band.

Dennis is mistaken for a recently released child molester; Mac tries to bond with his ex-con father, who can't take his eyes off a creeped-out Dee; and Frank moves out of the apartment he's been sharing with Charlie, and moves in with Charlie's mother.
