Tom: Er, Niles, can I speak with you for a moment?
Niles: Yes.
Tom: I was wondering, did I do anything that offended you?
Niles: No. [angrily throws pots into the sink]
Tom: Oh. It must be all in my head. But I sensed that you had a problem with me dating Frasier.
Niles: Well, if you must know... [long pause] ... I'm sorry, what was the question?
Tom: Do you have some problem with me dating your brother?
Niles: [pleasantly] No.
