MST3K episode "Santa Claus Conquers The Martians" airs 1991

One of the best television shows of all time riffed one of the worst movies of all time December 21, 1991 when Mystery Science Theater 3000 featured Santa Claus Conquers the Martians. Joel and the bots sit through a poorly-acted, poorly-written movie with a lame plot.  Martians kidnap Santa Claus and take him back to Mars because there isn't anyone there to give presents to the children. It marked the film debut of Pia Zadora.

Mystery Science Theater 3000 episode "Santa Claus" airs 1993

Mike and the bots were subjected to the campy, Spanish movie Santa Claus, December 24, 1993 on Mystery Science Theater 3000.  In this film, Santa Claus must deal with an imp from the devil who tries to brainwash Earth's children.  Viewers can really feel their pain!

Fortunately, Kevin Murphy appears briefly as the real Santa Claus!

One of the best lines: 

Narrator: [in film] Children from the USA...

Crow T. Robot: ...are too spoiled and lazy to help Santa!
