I'm a Saved by the Bell nut, but can't say I saw too many of the Saved by the Bell: The New Class episodes. And that's a good thing, because the series was quite awful.
In the show, Mr. Belding is still the Bayside HS principal, and Screech sticks around as his assistant. Zack, Slater, Kelly, and Jessie are gone, and they're replaced by a bunch of random crappy characters.
However, the show did include a cameo from current San Francisco 49ers head coach Jim Harbaugh. Wait, what?
The video proof of Harbaugh's cameo is below, but first, let Jeff G of Last Angry Fan explain the situation:
Screech's cousin (which would make Baltimore Ravens head coach John Harbaugh Screech's cousin as well!)... yeah, um, okay. Very believable.
Anyway, here's video of the episode (just skip to the 15:23 mark for the cameo of Harbaugh ):
