2. Stuart Minkus
Here's a big “Boy Meets World” offender. This one deserved its own spot on my list because it’s so bad that even the show made fun of it. Minkus was a recurring character, not just some background person we saw every so often, but out of nowhere he just disappeared. When Cory and the rest of his friends are graduating from high school Minkus showed up again and explained that he spent the rest of his school days on the other side of a hallway (one that was never seen on the show). He also mentions that he was there with a few teachers that had disappeared too. At least “BMW” had a sense of humor about it!
