Tornado Prom is the 91st episode and 15th episode of the fourth season of That '70s Show.
A tornado forces Eric and Donna to stay at the radio station, while the rest of the gang must hole up at the annual school prom. Hyde gets back at someone he hates, Fez gets his hopes high with Rhonda and Jackie questions her popularity. Meanwhile, Joanne starts to get on Red's nerves. At the end of the episode as the the Formans & Pinciotti are in the basement the reports on the television inform them that the tornado has passed and the warning was lifted with only one teen in critical condition, i.e. Forman in a coma due to driving at the tornado.
