Frasier: Sometimes it helps to write yourself a letter...
Tewksbury: He's already got himself on the phone.
Frasier: (frustrated) I don't know what he wants!
Tewksbury: Then why do you keep trying to bury him in psychiatric exercises?
Frasier: Because that's all I have!
(Tewksbury gives him a knowing, sad look)
Frasier: I'm sorry, caller, I can't help you.
