I might add that my high school class drove our teachers crazy with our attitude. I went to a military prep school from grades 9-11. My senior year the school gave up the military component. We just weren't taking it seriously, and the classes behind us were "worse".
There was a movie made after Animal House that appeared to have a very small budget. It wasn't as wild or funny as Animal House.
They did spend some money on the soundtrack and they did get Stephen Furst (Flouder) to play a role. It takes place at a military academy, is set a few years later in the 1960s, and manages to incorporate many urban rumors in the plot.
It was called Getting Wasted It can be found on some budget DVD releases. It isn't an outright comedy.
