Johnny Collins is the son of Lisa Collins in "I Can't Stan You". While his mother likes to show off her new boytoys she picks up while ignoring the kids, Stan likes to pull his gun on Johnny and shout hurtful, scary things, and in response, Johnny recoils and screams in a high-pitched squeal. When Stan finds out the neighbors think he is a jerk, he has the CIA take over their houses and sends them off to the Cornfield Motel. When Stan is eating nuts in his now-deserted home after banishing his family as well, when he chokes on one and runs outside looking for someone to help him but there is no one to be found. He collapses in the street but Johnny comes running and kicks him in the crotch dislodging the nut. Stan thanks him for saving his life but is confused because he thought Johnny hated him. Johnny says that just because he trash-talked him doesn’t mean he hates him. Johnny takes him to the Cornfield Motel where the neighbors are staying and shows him that they all trash-talk each other too. Stan feels better and becomes pals with Johnny.
Johnny Collins is voiced by Paul Butcher.
