Frasier: Say, where's Sam off to?
Carla: He's off to a luxury apartment to meet a naked woman.
Cliff: Boy, that guy leads a pretty exciting life compared to us, huh?
Norm: Cliffy, compared to ours, a tapeworm leads a pretty exciting life.
Cliff: You know, I happen to be a bit of an expert on tapeworms. It all goes back to my eighth grade science fair. Everybody else had rabbits and Guinea pigs. I had a tapeworm.
Norm: Really?
Cliff: Yeah, so I couldn't go. Or was that a ringworm?
Norm: Check, please.
Cliff: Uh... Oh, boy, oh, boy. Me and parasites, don't get me started.
