When Guenter has to decide between losing his intelligence and opting for "ignorance is bliss" or keeping the hat and being the smartest damn simian on Mars, he blows a gasket. And of course, Fry can relate. He and Farnsworth set down the hat and a banana to let regular-old-monkey Guenter decide his fate of being released into the wild or staying a smart monkey and the exchange is hilarious.
