Zwan. Lyrics listed are from the 12/13/01 late show. As for the song itself, the banter from before that performance:
BC: OK, we just wrote this song on the way up here.
MS: This is true, we were talking about uh... the four of us were in car... and somehow the subject came up about how we all enjoy each other's company, as men we enjoy each other's company. And then somebody said, yeah, chicks just get in the way. And then these guys, in between the first set and this set, they came up with this little number... which I will have nothing to do with.
