I happened to find this a few years ago when I bought a CD copy of Lady Gaga's Born This Way. Apparently, there was an additional verse that Gaga included in the lyrics to 'Bad Kids' and that she wanted to perform it on her Born This Way ball tour, but she never did. It's aparrently included in some early test pressings according to Gagapedia.

Not gonna post the whole verse here, but one of the highlights of the verse is this: "Manicure is slick, you mad that my tip's longer than your 8==D?"
