Sit in a corner in the fetal position rocking back and forth chanting, Santa Claus is coming to town, Santa Claus is coming to town…
Hang a stocking with your roommates name on it. Collect coal and sharp objects in it.
Paint your nose red and wear antlers. Constantly complain about how you never get to join in on the reindeer games.
Sing All I want for Christmas is your two front teeth…
Make anatomically correct gingerbread people and eat the best parts first.
Smoke mistletoe. Do what comes naturally.
Take some miniature marshmallows and put them in a little baggie. Attach a note to the bag that has a picture of a snow man and this poem:

You have been naughty, and heres the scoop

All you get is the snowmans poop!
