1. Pick one of your friends' icons.
2. Photoshop a Santa Hat onto it, as badly as you like.
Here's a batch for 2008. Comment if you're feeling neglected. New for this year, I might be able to drape sparkly tinsel on your icon instead if you ask nicely.
NB: if you have a *South Park* icon, or a *Lego Minimizer* icon, there are Santa Hats right there in the generator. You don't need me to do them.
