Frasier: ... What's on the pizza?
Martin: Ah, I thought so. All right, well now we've established you're middle-aged, take some advice: don't fight it, it'll go a lot easier.
Frasier: Good lord, Dad, what are you suggesting? I'm gonna rush off to a plastic surgeon to get an eye lift and a chin tuck? [examines his face in a silver plate] Oh, dear God!
