I think...I KNOW the stats from that link must be flawed in some way. Those red cups are what? 14oz? And you've gotta think that the drunker people got, the more foam they were getting into each cup, and the less actual beer they were drinking. On average, maybe 8 to 10oz of beer per cup. That's about 125 or less cans of beer. The average case is 24 cans/bottles..So..Ehrm..5 cases? I've comfortably drank 3 in a single sitting, and then gone out to buy more...And I've had a keg all to myself on the back porch of my appartment...It started floating after a few hours, and was completed after about 13hrs...The record time I've been around a floating keg was about 45 minutes with only 5 people drinking. Then again, we were also bonging the beer and using pitchers for cups. We also had plenty of cocaine in our systems, so that made the drinking much more tolerable.
