Detective Rick Diego, just wants one thing for the holidays: a functional restroom. Instead, he discovers the true meaning of Christmas... Aliens . Farnsworth still believes in Santa Claus, and he absolutely insists on sitting on the fat man's lap to get that sweet sweet candy cane. But when jolly old Saint Nick does a no show, it's up to the Division of Nerd Crime to save the day-and hopefully they can do it without peeing their pants... or each others.
