I honestly don’t watch a whole lot of Futurama. It just isn’t up there for me. However, I always seem to remember this particular episode and its repetitive use of the word “XMas”.
Fry longs for the traditional Christmas that he used to have in the 20th century, so his friends decide to help him celebrate ‘XMas’-the modern interpretation of the holiday. Advancements in robotics have produced a mechanical Santa that performs the duties of the traditional Santa Claus, including figuring out who is naughty and who is nice. Unfortunately, a glitch in his programming caused him to become a gun wielding psychopath who murders (who he interprets to be) the “naughty” after sundown.
Fry realizes that Leela has only sad memories of the Christmas and sets out to find her a great gift. After buying her a parrot, she soon shows up to rescue him from the homicidal Santa. Bender and his robot friends offer shelter, but before long Santa finds his way in and has to be thwarted by Dr Zoidberg.
He promises to exact his revenge.
Does he exact his revenge? Maybe I need to keep watching the show…
