Edit: Taken down! This was the Sesame Street appearance of Katy Perry, in which she sings "Hot and Cold" to Elmo. The lyrics were mildly changed, although the story--a boy who confusingly may or may not want to play with her--remains the same. Apparently, after filming and posting the video, Sesame Street belatedly realized that Perry wasn't wearing a whole lot of clothes in it. The pruriently curious can still see it at TMZ.
