A long time ago there where 2 Santa Clause’s. One who wore black and one who wore white. The white one gave good children gifts, while the black one played pranks on the bad children. As time went on the black Santa Clause’s pranks became worse and worse, to the point of becoming dangerous. Eventually the black Santa’s pranks ended up seriously hurting the bad kids, to the point of near death. The white Santa could not allow this to continue. He lured the Black Santa to his house and stabbed him to death. The blood from the Black Santa stained the white Santa’s clothing forever. That is why he wears red today.
