Description: Even if you don't want to listen to the song during the credits, skip to the last 20 seconds or so. There's a little extra bit at the end. Anyways, this is the skit from the end of the most recent Simpsons episode (Season 22, Episode 8: The Fight Before Christmas) in which they parody a Muppet's Holiday Special. With some extra Katy Perry, of course. I mean, how can you live without it?
