4 Xmas Story

Fry becomes homesick during his first 31st century Christmas, called "Xmas". His insensitive moping hurts Leela's feelings because she has no family to celebrate Xmas with, and she runs off in tears. Fry goes out to buy Leela a present to apologize, but the others warn him to return by sundown, or else he will encounter Robot Santa, a murderous robot who kills anyone he believes to be "naughty", which is practically everyone. Fry finds Leela and the two reconcile, but it gets late and they are attacked by Robot Santa on their way back home. Robot Santa tries to break into the building, but everyone teams up to drive him away. Everyone celebrates their victory over Robot Santa, who threatens to return next Xmas.
