This is how I imagine the show:
Mom: Girls, now that your father is dead, I have asked one of his brothers to move in with us.
Girl 1: Is it Uncle Henry Winkler?
Girl 2: Oh, I hope it's Uncle Tony Danza.
Mom: Nope. It's your uncle Howie Mandell!
Girl 1: (breaking character) Not really. Are you serious? Jesus Christ, why not just cancel us? It would be more humane.
Girl 2: (pulling out cell phone) Hello, Maury? Can you get me on the O.C.? A guest shot? Anything...?
