@LV: Doesn't have to beer, you can drink whatever really. At the Championships, they used water in the cups and then had the side drinks going.
@element: See I'm the exact same way, would not work. My buddy Sam's a master at getting the last one down.
I will say my proudest beer pong achievement was getting a complete shutout while playing some high schoolers from Ontario in the sunny pool courts of the Dominican Republic. And I was teaming with one of them, and he sucked out loud, so I had to hit every single cup by myself, which made the achievement even better.
