Bio-Dome

Bud "Squirrel" Macintosh and Doyle "Stubs" Johnson are best friends who live together. Their environmentalist girlfriends, Jen and Monique, stand them up for a date, due to their immaturity. Driving back home, they pass by the Bio-Dome, where scientist Dr. Noah Faulkner is about to seal his team in for a year without outside contact. Mistaking the Bio-Dome for a mall, Bud and Doyle go inside to use the bathroom, only to be sealed in along with the scientists. Dr. Leaky, the project's investor, discovers them and demands that they be kicked out. Dr. Faulkner refuses, claiming it would destroy the purpose of the experiment, and so Bud and Doyle remain. Although things go smoothly at first, this proves to be a mistake, as Bud and Doyle continue their antics, harming themselves and destroying many of the scientists' projects. The scientists plead to Dr. Faulkner, but he only relents after the two find a secret stash of junk food and experiment with laughing gas. Bud and Doyle are then banished to the desert environment section and after three days of being stuck, they discover a key in the lock of one of the windows, which opens a back door, and they escape the Bio-Dome.
