The frat-house game beer pong appears to be going big-time. Officials at the Flamingo Hotel in Las Vegas have announced they’ll be playing host to the 2009 World Series of Beer Pong, Jan. 1-5 at the casino/hotel. For those of you who don’t know — I don’t think the game was popular when I was in college — beer pong essentially involves tossing a ping pong ball into a series of plastic cups of beer. If your opponent gets the ball in one of your cups, you have to drink the beer. At least that’s the frat-house version. There are a variety of rules and regulations for official beer pong competitions, and drinking the beer isn’t always mandatory. I think what is mandatory to compete is to have nothing better to do with your time. Either way, here are additional details. Personally, I’d prefer to drink my beer not in plastic cups. And without having to pick a greasy ping pong ball out of it.
