Compared to some of the well-known party schools of the day, OU (that is the University of Oklahoma) is pretty tame, though the students still power down beer and liquour like it's going outta style.
Back in my days as an undergrad... (cue up dream sequence music... ooo-wee-ooo!

) it was not unusual to measure the popularity of parties at the Greek houses by how many kegs were at the party. The small houses (like us) could get by with one or two; most of the other houses had three, four or five-keg parties almost every Friday night. And functions (sorority/fraternity mixers) almost always included a keg or two, especially when the fraternities hosted.
Major parties like the Sigma Chi Derby Days and the Fiji Islander were open to the public back then, and it was not unusual for everybody to line up at the beer truck and tap straight from the truck. (3.2 beer, folks.) Beer distributors used to give away beer cups with Greek letters printed on them.
I remember back when I was a freshman at the dorms the last night 3.2 beer could be purchased by 18-year olds before it was jacked up to 21... most of the dorm floors were in a state of total drunken abandon until well past midnight when visitation hours were over. The hangover of the century followed!
