Quote from Frasier in Don't Go Breaking My Heart (Part 3)
Frasier: [out loud] Hello, God, it's me again. Dr. Frasier Crane. Listen, it seems that when we made our little arrangement, there was another deal in place. Now, I've had some experience with double-booking, and I know that the person who books first always gets priority. So, as long as Daphne keeps her end - which she is, to the letter - it seems our little arrangement would be rendered null and void. Ergo, I am now going to yell at my brother. ... Unless of course, you give me a sign. ... Very well, then. This is going to be sweet.
