actually, kegs are forbidden at cornell frat parties
in all seriousness, cornell is a very fun place, but that is paired with an intense academic environment. libraries are open 24 hours a day because there are actually people using them 24 hours a day, every day.
With regard to all your "non-serious" cornell traditions, i don't see why squid throwing is such a big issue for you. It's actually fish throwing, for the record, and it's part of the hockey tradition and the big harvard-cornell hockey rivalry. It all goes back to when harvard started it by tying a chicken to our goalpost mocking the ag school. We now respond by throwing fish at them because of their proximity to boston harbor.
