Quote from Frasier in Door Jam
Receptionist: I'm sorry Dr. Crane, you're not on the list, I can't let you in. Frasier: But I have an invitation. Receptionist: Yes, but you're not on the list. Frasier: Yes, but I do have an invitation. Receptionist: But you aren't on the list. Frasier: Yes, well, if I were on the list, I wouldn't need an invitation, I'd just say "I'm on the list." Therefore, the invitation supersedes the list. Receptionist: No, invitations are given out only to those on the list. Frasier: Ah-ha. But you do concede that I do have a valid invitation? Receptionist: Yes. Frasier: Then it naturally follows that I would be on the list. Receptionist: But you're not. Frasier: Then how did I get the invitation? Receptionist: I really don't know. You could have stolen it... Frasier: Are you accusing me of deception?
