Saved by the Bell S01E01 - Dancing to the Max

When the students of Bayside High learn that famed Casey Kasem will be hosting a dance contest at The Maxx, both Zack and Slater vie to ask Kelly for the chance to dance with her in the contest. However since Zack doesn't know how to dance, he turns to Jessie for help in learning how to dance so he can woo Kelly. However, after their lessons conclude, Zack decides to ask Jessie instead as a way to say thanks for his lessons. Meanwhile, Lisa reluctantly agrees to go with Screech after her date dumps her after she sprains her ankle.
