Nothing brings more joy to this atheist’s heart around Christmas time than seeing the season’s top two fictional characters, Santa and Jesus, doing a lounge act together. In this classic clip from South Park, Santa and Jesus are singing together in a night club, and Santa gets pretty peeved at Jesus. (This is the clean version of the clip; I have one where the expletive Santa uses is not deleted). Singers put out Christmas medleys all the time, but this is by far my favorite Christmas medley.
