I watch those 'fail' videos with some frequency.
Some, of course, are pretty ordinary stupidity. A face-plant while going too fast on a skateboard, for instance. You cringe. But it's not particularly entertaining.
But there are some that are just fascinating in the way that they're such an obvious set-up for disaster. And when it comes about, you find yourself thinking "Did you really expect that to turn out well?"
For a pretty smart guy, I'm fairly capable of being stupid. But some of those folks have me beat by many, many miles.
