Before we begin, here's a quick joke. Stop me if you've heard this one before.
So a guy is walking with a young boy into the woods. The boy says, “Hey mister, it's getting dark out and I’m scared." The man replies, "How do you think I feel? I have to walk back alone."
If you even remotely enjoyed that joke, I think it's safe to say you have a pretty dark sense of humor. And, as one study would suggest, that would mean you probably also have a higher IQ than the average person. So that's something.
