It's unfortunate that the presence of a TV camera sometimes causes people to act goofy, for no good reason. While watching a baseball game on TV in the '80s, the camera kept getting crowd shots in one section of the stadium. A spectator in the crowd was standing up, beaming from ear to ear. At first, I thought, "He's just being a ham for the camera." When he was still standing there beaming an inning later, I thought, "That's going on a little long, but maybe, he just really wants to be on TV." When he was still standing there with a fixed, maniacal grin one inning after that, I thought, "Did he just escape from an asylum?"
I doubt I'm the only viewer who wondered that.
