Mr. Awesome has the McSweeney's Joke Book of Book Jokes checked out from the library right now, which contains "The Grad Schoolyard Diarrhea Song." He read me the first verse out loud:
When you're analyzing Joyce
And your butthole has no choice
I laughed at that so hard I cried. I see McSweeney's has also been kind enough to put the whole thing online so you can sing it at home.
p.s. I know, I know! More wedding, less buttholes. I'll get to that post soon, I promise.
