Fine, spoil the joke!
Maybe it was the buildup, but I didn't find the versions of the joke by most of the standard comics all that great-- it's shocking to find that my imagination was more baroque than most of theirs. (Well, not Andy Dick's or Taylor Negron's, to be sure.)
I actually thought the women who, in one way or another, mocked and deconstructed the joke as boys' humor came off the best-- Whoopi Goldberg's version was more imaginative (and better timed) than most of the guys', and Sarah Silverman's take on it ("I actually was an Aristocrat") was absolutely brilliant (as was the trailer for the upcoming movie with her, which looks downright terrifying).
What's that? Keep it on food? Uh, no Marcello's for me, but I'm making pesto all'Antonius right now...
P.S. ...which the kids loved! (Didn't hurt that the pasta was called "train tracks.")
