Fry attends Mars University with the intention of dropping out of college and becomes the roommate of Guenter, a monkey who is made intelligent by an electronium hat provided by the Professor. Fry becomes bitter rivals with Guenter and humiliates him during the parents' reception party by releasing his unintelligent, feral parents, which makes Guenter unhappy about his current lifestyle. Guenter gradually becomes stressed to the point of taking off his hat and fleeing into the Martian jungle. Fry, Leela, and Farnsworth find him and try to make him choose between an intelligent life and the life of a normal monkey, but the three are swept into a river by Bender during a raft regatta. Guenter falls off a cliff after saving the three from falling over a waterfall using the intelligence provided by his hat. The hat breaks his fall and begins working at half its usual capacity, and Guenter becomes content with his now average intelligence.
