I visit a lot of weird websites (for reasons that I will not go into) that have weird forums with weird people and one thing that is common across all these very different places is that everyone has to have a cool avatar.

My favorite ones are the animated GIFs that play like a little thumbnail video.
It's pretty funny to see a comment posted by someone who has two geeky little kids dumb-dancing underneath his name.
Here's a small selection (personally, I like the buttcrack kitty-sniper).
