(BTW, I really like the PU tee-shirt I got: It's the Featuring Nico cover with an anchovy instead of a banana on a tie-dye).

I saw Pizza Underground play and they did do a rendition of "Movin' Out" as "Pussin' Out" because (I think) the pizza lyric novelty does eventually wear pretty thin and they're trying to mix it up a little. They also did Nirvana songs in the past tense ("Came as You Were").
