I need help choosing a song, a crazy song :)?

Blah Blah Blah by Ke$ha is kind of crazy. Actually any of Ke$ha's songs would probably be good for that. Haha. But I think Britney Spears is a good choice as well. Especially her songs on the same CD as Piece of Me. Also "Le Disko" by Shiny Toy Guns sounds like it might be appropriate. =)
