I was friends with MC Frontalot before anyone knew who he was, although not by very long.
I went to Highland High School, which is the school that Mike Judge named the one in Beavis and Butthead after. However, Judge actually went to St. Pius X, a private Catholic school, and apparently B&B's "Highland" is modelled after that (it bears no similarity whatsoever to Highland). But one of my teachers at Highland had previously taught at St. Pius, and had a story (I'm not sure how true it was, as he wasn't a very reliable narrator) that Judge was one of his students. It's a pretty stupid story though, and I'm pretty sure he made it up and only told it to try to get "cred." (It didn't work.)
In the mid 80s, Nintendo had a "kids design video games" contest. My friend Ben had an idea for a mathy edutainment game that was sort of like Flatland. Our classmate Justin stole it from him and submitted it. Justin ended up winning the contest and got on the local news and everything. I don't think Ben ever let that one go. Ben's apparently a realtor now according to LinkedIn. I have no idea how that happened. Or what happened to Justin. I can't find any information about the game design contest on the Internet anyway.
I had a lasting impact at my high school that nobody even knows about. In my English class, we read "The Milagro Beanfield War." One of the characters in it is a sad-sack nerd named Herbie Goldfarb. Being a sad-sack nerd myself, everyone in my class started calling me "Herbie." Somehow that spread outside of class, and everyone would shout, "Yo, Herbie!" at me whenever they saw me. Somewhere along the way, it just turned into a weird generic greeting people shouted at each other. Then a few months later there was a vote for what to name the brand-new on-campus convenience store.
Guess what won.
My dad went to high school with Mandy Patinkin.
