Quote from Niles in Desperately Seeking Closure
Frasier: Oh, by the way, Niles. Do we have plans for tonight? Niles: Yes, why? Frasier: Well, I'm afraid I have to cancel. It's my one month anniversary with Sam, I'd like to take her to L' Escalier for dinner. Niles: I understand, of course. One month is quite a milestone. Thanks for the reminder. I need to change my water filter.
