Sometimes you just can't make this kind of thing up. Big thanks to Reddit user timberspine for coming across something truly awesome. This video is from Saved by the Bell: The New Class, and features then Indianapolis Colts quarterback Jim Harbaugh as Screech's cousin. We get to see Coach Harbaugh enjoying some cheesy lines, as well as the always necessary life lesson. And any time you can get introduced as Screech's cousin? Well that's winning if I've ever seen it.
The video is cued up to Coach Harbaugh's main scene, although you can catch some more life lessons from Jim Harbaugh at the 19:00 minute mark. This kind of video is exactly why YouTube is so freaking awesome. And I'm sure it is one more reason Jim Harbaugh doesn't want to talk about his playing days. Had this been the original Saved by the Bell, I'd imagine he might be more inclined to talk about. Whatever the case, enjoy!
