James Franco  bared his rump for a good cause on Sunday night, when he was stripped by drag queen Bianca Del Rio during Broadway Bares: Rock Hard, the Great White Way's skin-baring event to raise money for AIDS research and education. During a skit, James — who stars in Of Mice and Men on Broadway — got sassed by Bianca and pulled the "do you know who I am?" card on her. She responded by saying she needed to do a "background check," which involved him dropping his trousers. Needless to say, the sight of James's bum was met with more than a few cheers from the audience. Watch the whole exchange above.
