All right this one is just too funny.  You can make Santa get down and dance.  You pick the music, the moves, you can even upload your own face over top of Santa's.

Here's a verision that I put together for Santa (Sugar Daddy, Bust it, Sprinkler, MC HO-HO, Thrilla, Chimney Shimney)  I did unlock the Pulp Fiction option, but couldn't find the other secret option.

If you want to build one of these yourself, check it out at this great site from OfficeMax.

I'm having more fun with these silly flash sites than is right especially this one North pole dancing. If you put together a good version yourself, drop the html link in the comments.
