First off, don't do it. But since you're young and idiotic, you'll ignore this advice.
Second, we (myself and other young fraternity idiots) used to have a competition called 200 club where one would drink a shot of beer a minute, attempting to reach 200. If you do the math, that's 16 2/3 beers in 3:20--a marathon of sorts. Bathroom breaks were allowed, but monitored for purging. Once you puke, you're out.
The first to go were the ones who loaded up on bread, thinking it would "soak up the beer." Next were the ones who ate too many lil' smokies at dinner. I ate light and just focused on the task at hand. Don't remember much past 120 or so, but was told I accomplished the task, resembling a lobotomized man drooling, unable to speak, and needing help to drink the last ones. To celebrate my "victory," I vomited for a day. Fun times.
Oh, and don't attempt unless you are at least 1/4 Irish.
