Jerry: There are many things I think you can point to as proof that the humans are not smart. But my personal favorite would have to be that we had to invent the helmet. What was happening, apparently, was that we were involved in a lot of activities that were cracking our heads. We chose not to avoid doing these activities, but to instead come up with some device that would help us continue enjoying our head-cracking lifestyles. The helmet. Even that didn't work, because not enough people were wearing them, so we had to come up with the helmet law. Which is even stupider because the idea behind the helmet law is to preserve a brain whose judgment is so poor it does not even try to stop the cracking of the head it's in.
