Each professor gets to give an introductory account of his or her discipline then a brief rebuttal to the others. At the end of the debate, the audience votes and the lucky winner claims the Oar and climbs aboard, waving goodbye to the others. Often, a seventh participant, the Devil's Advocate, appears and tries to convince the audience that the entire panel is unworthy and that all should be left behind to drown. In the following year, the defending champion faces five new challengers in a new debate. To date, no one has successfully defended the Oar.
