Futurama, Season 6

Fry:
Can someone please explain how you celebrate this crazy holiday? Preferably in song?

Robot Santa:
[singing] It's the violentest season of the year.

Elf:
Old Kringle-bot has come to spread some mugs of Xmas fear.

Robot Santa:
Sugar-plummy visions will be dancing in your head

When I cane you from the comfort of my sled.

Leela:
On Xmas Eve, we don our gay apparel,

Kevlar vests, asbestos stockings and a barrel.

Prof. Farnsworth':
And if Grandma's Xmas fruitcake finally reaches critical mass,

It can be re-gifted straight to Santa's ass.

Robot Santa:
But the ornamental armaments are merely superficial,

The tinsel and the trappings are just icing on the missile.

The one thing that you need to make your Xmas day splendiferous

Is a pine tree; a pine tree that's coniferous.

Planet Express crew:
We have to have a pine tree as coniferous.

Robot Santa:
[flies away] You're welcome.
