Plot hole: Zack was told by Slater that Kelly was excused from going to detention by Belding because Belding found out she saved Screech's life... Yet only 3 students knew about the fake "choking" stunt - Zack and Screech did this stunt to get Kelly into detention (so they wouldn't have said anything), and Kelly unlikely would say anything as generally students will say anything to get excused and usually are ignored by the teacher or principal who use authority to make the student's detention stand. So who else could have told Belding?
Saved by the Bell (1989)
1 plot hole in King of the Hill - chronological order
Starring: Mario Lopez, Mark-Paul Gosselaar, Dustin Diamond, Lark Voorhies
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.
Zack: You know, I've finally found out the best thing about high school, once you graduate you don't have to come back.
Trivia: Of the main six characters, Screech is the only one whose father never made a physical appearance on the show.
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.
