Back in the day when "alcohol" wasn't a dirty word on our campus...
We had a "drink on every floor party" in my dorm. We had 4 floors, and my floor was upside-down Margaritas. Just some Tequila, Margarita Mix, the person sits in a chair and leans back. Pour a shot of each into their mouths, swish, and swallow. Needless to say, after that, most people didn't make it much further!
