An argument that broke out at a national debating competition last week led to a long-haired, hippiesh Kansas City professor dropping his pants and mooning the room, reports CBS. Of course, this was all captured on tape and dutifully YouTube'd. (There's an university investigation brewing, thanks in part to the vid.) There was also a racial tinge to the argument, which was about some dorky thing like improper use of body language during the debate. The delightful video is after the jump; the mooning incident occurs right away. The graybeard professor jumping around barefoot, screaming expletives, is worth the cost of admission.

Not surprisingly, Professor Shanahan has a history of acting out. His more notable arrests, according to Hays Daily News, include assault and battery at a T-ball game, and battery "after an argument with his eye doctor."
