Mark and Slater both try to obtain Rebecca as a dance partner before the big dance contest at The Max. However, Mark goes with Tom instead. Evan also has a date for the dance, but when she sprains her ankle, he backs out. Screech agrees to dance with her in the contest despite her injury. In the end Screech and Lisa win with their dance move, coined by Casey Kasem as "The Sprain"
