Futurama Episodes

While the crew takes a vacation skiing, Fry becomes depressed by how much Christmas has changed in the future. Besides the difference in pronunciation and the extinction of pine trees, jolly St. Nick is now a man to be feared. It’s Fry’s first Christmas away from home, and he has no one to share it with. Leela is also feeling lonely; growing up as an orphan has left her with no family to share the holiday. Fry is determined to cheer her up, so he goes out to find her the perfect gift. Everyone warns him to be back by sundown lest he be killed by Santa. But when Fry’s gift, a pet parrot, escapes, he neglects their warning trying to capture it. Leela then learns of his absence and runs out to get Fry before Santa Claus does. The two unite to confront the Xmas enemy.

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.
