Most students think their teachers are from another planet. For the students of The Faculty, they actually are. When Herrington High School's biology teacher Professor Furlong (Jon Stewart) becomes infected with a "killer" parasite, his lesson plans drift from science to science fiction. While trying to infect the film's central gang, the teacher loses his fingers to the blade of a paper cutter before being stabbed in the eye. Might not want to quit your day job, Jon.
