One time a buddy and I had a beer bong race. You could piss, but if you threw up you were done. I guess I did 19 in less than two hours. He did 18, threw up, and came back to do the other one just to say he did apparently. Don't remember the end of that because I was all kinds of fucked up. I know we casually drank a few before that, but that was not very smart.
