There’s an episode of the Simpsons where Lisa performs a science experiment comparing the relative intelligence of her brother and a lab rat. The rat learns quickly that the cheese is hooked to electrodes and stops trying to eat it. The brother doesn’t.

You hear stories about things being stolen for their value as scrap metal. Statues, plaques, etc. Some of the really stupid guys go after electrical wire, while it’s still electrified. In all cases I’m aware of, they cause serious injury to themselves, and never succeed in their task. And yet, they keep coming back.

How can humans be that stupid?
