You should really go over here to see 2006's best music videos. Lots of good stuff on that list. But I wouldn't know. I'm studying for finals.
UPDATE: This could be good enough for its own post, but I decided to add it on to this one. Go watch Tommy's 12 Days of Christmas, which was made by Joel Veitch, the guy who brought you dancing kittens, the sponge-monkeys, and everything else you hold sacred in life. I mean, seriously, it's got cross-dressing dogs and David Hasselhoff in it. That alone would be worth your time. And, it's even for charity. Go watch it, suckas.
On another note, check out the alternative to a cease-and-decist letter that this guy pulled off against Microsoft. Mass hilarity. Be sure to check out the image he "swapped." Cough.Goatse.Cough.
