If you go to http://www.adultswim.com/ , there's a banner across the main page that says if you find Mr. Poopy Butthole in the portal, you can win.
I clicked the portal about 50 times, and eventually found him. Clicking on him said I won a T-shirt! It had me put in my name and address too. He showed up on the lower right side of the screen, and covered maybe the bottom third (he was really noticeable and out of place, is what I'm getting at).
If you find him too, post what reward you get, I'm curious if they're all T-shirts. I regret not copying the rules or a pic of the T-shirt I won, so if someone else could post that, that would be great!
