The "big score" that Bender tries to pull off is actually to steal Zap Brannigan's entire crew and convert them to Planet Express employees. What he doesn't know, however, is that since Leela hesitantly tags along, she is accidentally hypnotized by the hypno-toad to fall in love with Zap, frustrating Fry to no end. Fry then complains to Bender that the so-called "big score" is an utter waste of time, and the entire crew quickly gives up and returns to the Planet Express HQ without Leela. In a miraculous twist of events, Leela's hypnotizing wears off, and somehow escapes Zap's ship all by herself. After returning, everyone's too shocked to understand what just happened, so they all decide to enter the professor's new mind machine to erase this memory. Turns out, none of this ever happened!
