The Prom-centric episodes were alway amongst the most exciting episodes of the show, because they brought the main core cast members together. They were also written by the best writing staff. This episode is no exception. What I love most about the episode is that the 3 main couples of the show are together - in different ways, of course. Lisa finally accepts Screech's offer of a date, which has a hilarious outcome when the gang join them to the movies. Screech's unrequited love for Lisa always brought comic relief to the show. Jessie and Slater agree to go to Prom together because they have no dates, and find they have feelings for each other and become centre spotlight when they dance together, despite being total opposites. And most importantly, Zack and Kelly finally become a couple and share their first kiss. Zack does something really romantic for Kelly in this episode because she cannot afford Prom, and it's always a pleasure to see these two be so loving with each other, because they had such great chemistry.
Definitely a memorable episode, a strong episode for the central couple, and my favorite SBTB episode of all time.
