Fruit Punch whatever flavor + 7Up bottles for adjusting the alcohol content....
Little did anyone know the dept secretary was too embarrassed to bring the Absolute Ethanol bottles (200 proof) to the party so she was emptying out the 7Up bottles and refilling with abs. ethanol. The Profs couldn't believe how strong the punch tasted so kept diluting with more 7Up!

I'll bet that punch ended up around 150+ proof!
My only regret is I was having a little drinking competition with fellow students, still not sure how I walked the 3 miles home...
