Marge: I'm afraid we're going to need a bigger house.
Homer: No, we won't. I've got it all figured out. The baby can have
Bart's crib and Bart'll sleep with us until he's 21.
Marge: Won't that warp him?
Homer: My cousin Frank did it.
Marge: You don't have a cousin Frank.
Homer: He became Francine back in '76. Then he joined that cult. I
think her name is Mother Shabubu now.
