(An isolation-suited Dr. Dietz enters Stu's room with a small animal cage)
Dr. Dietz: I'd like you to meet a friend of mine. Meet Geraldo.
Stu Redman: Geraldo, huh?
Dr. Dietz: Um-hmm. Now, the virus your fellow townspeople contracted passes easily from human to guinea pig and vice-versa, presumably. But Geraldo has been breathing your air, via convector, for the last three days. And Geraldo is fine and frisky, as you see. I'd call that rather comforting, wouldn't you?
Stu Redman: I see you're not taking any chances.
Dr. Dietz: That's not in my contract. However, it does appear there is absolutely nothing wrong with you, Mr. Redman. Or, may I call you Stu?
Stu Redman: Just don't call me Geraldo.
