Penn’s finals ended today, which means that now everybody is home with not much to do. Sure, you can shop a bit with your mom, and see all your high school friends, and drive around your town in your old car…but that all gets boring in about three hours.

So what can you do when you’re lounging around your house in ripped sweatpants and your retainer? You can Elf Yourself.

Elf Yourself is not some kinky Christmas-themed porn video, despite how it may sound. On the contrary, it’s an amazing website powered by JibJab (you know, the Office Max emblem that looks like two brothers from the 1800s…for some reason…) through which you can, well, Elf Yourself.

You upload pictures of you and up to four of your friends (or random people if you want to be a real creepster) and superimpose the faces onto festive little elves, all decked out from little twinkly-toed slippers to furry coats to Santa hats.

Then, you can choose one of four fabulous dances to have your elves cyber-perform: disco, country, Charleston, or classic. If you’re really into it, you can even order mugs and mouse pads with pictures of you and your elftastic friends.

I’d recommend choosing pictures in which your face looks confused, elated, angry, constipated, or distorted in any way, because you’ll definitely be disappointed if you just pick a boring smiley face.

FYI, the disco one is my personal favorite – there isn’t anything quite like seeing my dad shimmy in striped leggings.
