Plot hole: Lisa, Zack & Screech all talk to JB as if they have known her since she was little. However, they have only known Slater for approximately four years, so them knowing her from a little girl, as implied, wouldn't be possible.
Factual error: When Zack is given the old newspaper with Mr. Belding's article, the headline reads, "Picture on pages 3 and 4." When he looks at the picture, he looks at the middle of the paper, with quite a few pages at both sides of the newspaper. Pages 3 and 4 would be near the front and would be on opposite sides of the same page.
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: At the start of the episode "No Hope With Dope", Lisa runs into the hallway with exciting news, and Zack responds to Lisa using a sentence ending with "you'll crack your makeup." The audience (primarily young females) starts screaming and cheering very loudly to that line. I am trying to understand what about that "crack your makeup" line was there to scream and go ga-ga about.
