Despite Katy Perry being axed from Sesame Street last year, she still managed to get invited to hang out in The Simpsons Christmas special. The promo pics are genius. Burns... so sly, so filthy, so old. Not sure what Perry is doing (perhaps singing), but it seems that despite lending her name to the episode, she has not been immortalised in the famous yellow. At least the jokes about boobs will fly over the kids heads. This time.
