Frasier: Niles, refresh my memory. Why are we wearing plastic snouts and a tiny little wading pool around our waists?
Niles: Oh, you've forgotten. That Halloween we went as "The Bay of Pigs."
Frasier: Ah! Yes, as I recall nobody got it. We finally had to take to telling that we were "Swine Lake." They didn't get that either. That was a long evening.
