You may see (or be one of) over 400 drunk, awesome nerds in Hogwarts uniforms stumbling around Capitol Hill tonight. It's the Third Annual Triwizard Drinking Tournament for locals and folks who came to town early for this weekend's Penny Arcade Expo. They're raising money for Child's Play, issuing arcane challenges, and trying to score the most points for their House. Sadly, enrollment is closed, but boozy wizards are friendly wizards, so say hello and you might wake up between two Dumbledores tomorrow morning.

Oh, and hey—if you're going to PAX this weekend, you may want to pull down this iPhone app or this Android app to help you with scheduling and keeping track of what's where. Both free, both handy, both great for navigating the mega-show with whatever brainpower you've got left after tonight's Tournament.
Thanks, Slog Tipper Tom!
