There are many things you can point to as proof that the human is not smart. But my personal favorite would have to be that we needed 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 those activities but, instead, to come up with some sort of device to help us enjoy our head-cracking lifestyles.

What would the world be like if people said whatever they were thinking, all the time, whenever it came to them? How long would a blind date last? About 13 seconds, I think. Oh, sorry, your rear end is too big. That's ok, your breath stinks anyway. See you later.

Anyone who would laugh at a recital is probably some sort of lunatic anyway. I mean, only a sick, twisted mind could be that rude and ignorant.

Isn't it weird that we drink milk, stuff designed to nourish baby cows? How did THAT happen? Did some cattleman once say, "Oh, man, I can't wait till them calves are done so I can get ME a hit of that stuff."

If professional wrestling did not exist, could you come up with this idea? Could you envision the popularity of huge men in tiny bathing suits, pretending to fight?

Boy, I miss the days they made toys that could kill a kid.

Once you start doing only what you've already proven you can do, you're on the road to death.
