Norm: All right, okay, here's one. Hayley Mills, playing herself and her twin sister in The Parent Trap.
Sam: All right, all right. Um, how about Elizabeth Montgomery as both Serena and Samantha in Bewitched?
Norm: Ooh! Very nice!
Cliff: Yeah. Yeah.
Sam: All right. Cliffy?
Cliff: Well, uh, Norm, I'd have to say the, uh, queen of the genre, Patty Duke, as both Patty and, uh, the minuet-lovin' Cathy.
Frasier: Oh! What's the topic du jour? Actresses who have played their own look-alikes through the use of trick photography?
Norm: No. Fictional twins we'd like to see making out with each other.
