It was just under a post wishing the board a Merry Christmas, so it didn't really have a title. So every year I've posted it, I've just slapped one on it at the time and whether it was ever called "A Very Parodyverse Christmas" or whether I just mistakenly stole the name, I just don't know.
In any event, it's a fun round robin and proves that Christmas in the Parodyverse is always entertaining.
