Classic! Watch Jimmy Fallon, Rashida Jonesand and Carrie Underwood perform a holiday medley with some of this year's most popular songs.

Lyrics include:
I feel like I weigh a ton
My pants are coming undone
Turn on that microwave, son
We're up all night to eat turkey
We're up all night to eat turkey
We're up all night to eat turkey

...and

Outside the WalMart
Outside the Kmart
Outside the Target
(But there's some) Good buuuys!

You better hurry
You want that Furby
What rhymes with Furby?
