Continuity: Zack messes with the piano so it will give him a chance of winning. When Tori plays it sounds like she is messing up. But immediately following that screech plays the piano with no problem and there was no time to fix the piano.

Trivia
During the final 2 seasons of Saved by the Bell, most notably the season with Tori and the one following it, look for actor Casper Van Dien in the background of some episodes. He appeared in many scenes throughout the final 2 seasons as a random background extra, most notably in the locker hallway scenes. This was before he made it big in Hollywood. See more...
