I stumbled upon this today. It's really entertaining. It's about a guy who got one of those obnoxious singing/dancing santas from Wal*Mart and changed what it had to say. There are videos at the bottom of the page. Above the movies, there's a very complete and detailed discussion of what he did, and how. The details definitely appeal to the geek in me, which, truthfully, comprises most of my self. So I liked reading about it. Your mileage may vary.
