I saw that episode, too. I don't think it was the pilot, though, because of a particular exchange between Frasier and Niles that wasn't contained. It's long stuck with me:
F: Yes, I know what you think about everything. When was the last time you had an unexpressed thought?
N: I'm having one now.
Kind of says it all, when listening to gate agents, or $MIJ, just prattle on and on. And on.
