Earl gets so upset by inaccuracies in a game of ""dinosaurs"" Jeopardy that he decides to give the students a first-hand account of the early Mesozoic era by filling the halls with computer-generated velociraptors and T-Rexes! None of the kids know how to get rid of these massive monsters, except for Marcus, but he lacks the confidence to express his ideas. Only when he's urged to speak up does Marcus voice his plan to freeze the school and send the dinosaurs to the only local source of heat: Earl's boiler room! Marcus' plan saves the school and helps him build the confidence to express himself.
