I think Jess was just using that as an example of shows that have characters one episode characters dissapear for no reason, and in this case managed to make fun of it.

Any way, back to Saved by the Bell for those who are interested, here are a few scenes that I remember liking, be warned I tend to remember trivial things, sometimes I'm not even sure what the whole episode was about, just the scene.

1. In the second graduation episode, after everyone else finds out Zack cheated to win the chance to sing a song for Bayside, they get him to drink something (not sure what) and his song comes out all garbled and weird, the backing singers jokingly sang the same things he did. I really want to see that again somehow...

2. Screech sees Lisa stand up and spread her arms out and run towards him in slow motion, set to romantic music so he does the same. The two of them run (in slow motion) to each other like two lost lovers as the music continues to play in the background... and then Lisa runs past Screech and some random guy we don't know appears suddenly with his arms spread out, and he and Lisa hold each other ( she was running to him, not Screech) and Screech runs back to his seat in sped-up motion.

3. Mr. Belding's brother arives at the school and someone (I think Screech) says something like "Two Beldings in one building, and one of them is balding."

That's all I can think of for now, but I'm sure there's more.
