I've spent the last 10 minutes looking at these great costumes on collegehumor.com. Just keep clicking on the pictures to see new ones. I have no idea when it ends.
Two samples that are at least tangentially related to TT:
Beer pong:

Duke lacrosse guy (somewhat tasteless, but I haven't offended anyone in a while):

I went to the Halloween in the Castro street festival dealie (insert Chris-is-gay joke here), a huge, 250,000+ person (not a typo) clusterfuck of a party. Anyway, some dude was full-on Duke Lacrosse, cleats, apparently real shorts, an authentic-looking practice jersey, pads, etc. I would have talked shit, but he was like 6' 4" and was carrying a lacrosse stick, so I thought better of it. I consoled myself with the fact that said stick probably found its way halfway to his spleen before Wednesday morning. I mean, he was from Duke and it was the Castro...

Oh right, nevermind, I get it now. It's funny 'cuz they kicked the shit out of that stripper. Sorry, I was blinded by t3h gayness.

Also, if you want to see what the kids at UMD are doing . . .
