When I was studying Engineering in the early '80s, we used to have the "24 Club" and the "48 Club". You started with the 24 Club, which meant you had to drink 24 beers at one sitting, without sleeping, passing out, or puking. The same with the 48 Club, which was 48 Beers. There was no time limit, and I made the 48 Club in just over 20 hours.
Keep in mind, this was Canadian beer at a 5.5% alcohol content!
These days, I drink a 6.2% beer, and usually put back about a dozen on our Friday beer nights
I don't drink at all the rest of the week, so I am what they call a binge drinker!
