Here's my story. It's not about the worst quantity wise. But you'll see what it has merit.
During my college years, me and my fraternity buddies loved to play a game called "beer pong". Do not confuse this with "Beirut", which is where you throw ping pong balls into cups. Beer Pong to us is played with 6 FULL red cups, 2 teams of two players, and ping pong paddles. The rules are pretty intricate to explain here in full, so I'll refrain from that.
It was the beginning of spring break. My college had a different schedule then most, so our spring break usually came about 3-4 weeks before the conventional time for spring break. Most of the other guys had gone home already, so there was maybe 10 of 40+ left in our two houses. It was evening and we wanted to get drunk. Problem was there was no supply of beer and none of us were of age to go out and buy any. Bummer. So what do we do? scavenge! We searched every inch of our house for whatever we could find.
You need twelve full cups per game. What did we use? A handful of cans of old Natty Ice, some Busch, a couple bottles of Mike's Hard Lemonade, a couple cup's worth of cheap red wine, I believe some Sierra Nevada Pale Ale, and a bunch of Bud Lights. This fine menangerie of alcohol types allowed us to play two games. Not so bad, until the morning. Worst hangover headache of my life. Of course, I saw it was coming a mile away, but I was so bored that I allowed myself to do it anyway.
In terms of sheer quantity consumed - half a bottle of Saki, a bottle of red wine, a couple beers, and one or two mixed drinks over the course of ten hours. Mixed with another intoxicant, it made for a very fun time.
