So, I was rewatching the Office for the 14th time, and I noticed a writing error. In "Safety Training," Kevin bets 10 jellybeans are in a jar, and this is wrong. BUT, later in "Work Bus," he is shown to be able to do math perfect if it involves junk foods. So, yeah. An error. I mean, I know the Work bus one was a small, one-off joke that was like, 6 seasons later, and they didn't plan it probably, but it's still a small error.
