I've never been in one, but this reminds me of a story...
It was some colledge kid's 21st birthday, and bars around here (Minnesota) used to have something called the "power hour", where, when you turned 21, they would serve you 21 shots in an hour (if you payed for them, of course.) So, the guy and his buddies walk into a bar and begin the power hour. He got through 17, went back home, and DIED.
His BAC was around .53. Poor bastard. Now, bars can't serve you on your 21st birthday (from 12 AM to 2AM - closing time.)
