Frasier: Dad, look, you know, I really don't feel like going out on my birthday this year.
Martin: are you sure?
Frasier: Yes, I actually had made plans already. I was gonna stay home and watch television. The opera is mounting a new production of "Cosi van Tutti."
Martin: Oh, well no wonder then. Well, okay, but you're missing a real treat. Duke said in the finalé, the whole cast skates to the top of this ramp, then splat! Right into a tank of whipped cream. Bet they don't do that at your opera.
Frasier: No. And Mozart's still kicking himself.
