Futurama, Season 3

Neptunian elves:
We are free and fairly sober

With so many toys to build

The machines are kind of tricky

Probably someone will be killed

But we gladly work for nothing

Fry:
Which is good because we don't intend to pay

Neptunian elves:
The elves are back to work today

Hooray!

We have just a couple hours

To make several billion gifts

And the labor isn't easy

Leela:
Then you'll all work triple shifts

You can make the job go quicker

If you turn up the controls to super speed

Fry, Leela and Bender:
It's back to work on Xmas Eve

Neptunian elves:
Hooray.

Leela:
And though you're cold and sore and ugly

Your pride will mask the pain

Fry:
Let my happy smile warm your hearts

Neptunian elf:
There's a toy lodged in my brain

Neptunian elves:
We are getting awfully tired

And we can't work any faster

And we're very, very sorry

Bender:
Why you selfish little bastards!

Do you want the kids to think

That Santa's just a crummy empty handed jerk?!

Then shut your yaps and back to work!

Neptunian elves:
Now it's very nearly Xmas

And we've done the best we could

Fry:
These toy soldiers are poorly painted

Leela:
And they're made from inferior wood

Bender:
I should give you all a beating

But I really have to fly

Robot Santa:
If I wasn't stuck here frozen

I'd harpoon you in the eye

Neptunian elves:
Now it's back into our tenements

To drown ourselves in rye

Leela:
You did the best you could I guess

And some of these gorillas are okay

Neptunian elves:
HOORAY!

Random elf:
We're adequate!

All:
The elves have rescued Xmas Day

Hooray!
