Marcus spends so much time with his latest creation, the ""Pal 9000"" minicomputer, that Billy feels left out. But Billy's not the only one irked by Pal, for Earl sees Pal's prowess as a challenge to his own supercomputer! Earl shows off his techno-might by turning the school into the edu-station of the 23rd century: a facility run by a computer gone berserk! Marcus uses Pal to take over the building's errant computer, but Earl strikes back by infecting Pal with a virus, causing him to attack students with the building's desks, chairs and doors! Billy tries to warn Marcus that Pal is infected, but Marcus, thinking that Billy is just jealous, refuses to listen. Only when Marcus sees his friends under attack does he finally take action, cleansing Pal with an anti-virus program. With the help of Billy and Marcus, Pal travels through cyberspace into Earl's computer and completely destroys it, saving the school!
