I was part of an epic snowball fight in December '84 or January '85. There was so much snow that the University actually cancelled classes that day.
I lived in Clement Hall. The fight lasted about two hours, ranging back and forth across Cumberland Avenue. The biggest battles occurred for control of the pedestrian bridge over Cumberland. I remember two or three KPD cruisers stopping to tell us to break it up. One of the officers was *ahem* brave enough to step out of her cruiser (leaving the driver's side door open) and loudly state "The next person who throws a snowball is going to jail!"
There were about fifty of us standing on or around the bridge at the time. It took her about ten minutes to get all the snow out of her cruiser by the time we were finished.
I remember not being able to move my right arm for a day or so after that fight. It just don't get much better than that day.
