Pipe Dreams - S3-E11
Deliberate mistake: When Zack brings an oil covered Becky to the biology teacher, you can see that it's a fake duck.
Visible crew/equipment: After the fashion show when Zack says "Sorry Lisa, I don't know what to say" an entire boom microphone assembly is visible and snatched out of view at the top of the screen.
Lisa: Yeah, 'I have all these problems and there's no-one ever there for me. I talk and talk and talk but no-one ever listens.'.
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.
Question: What happened to Kelly and Jessie in the episodes with Tori? Can someone explain what went on there.
Answer: As far as I can tell Jessie and Kelly decided to leave the show because their contracts were up and they wanted to pursue other things. But there were still episodes of Saved by the Bell left to tape so Tori came along to fill that void. Jessie and Kelly were supposedly still at Bayside, but they were "off-screen." The Graduation episode was filmed before Kelly and Jessie left the show.
