crazy? or bluetooth?

A homeless man walks by talking to himself. You think, “Wow, he must be crazy.” He turns his head and, surprisingly, has a bluetooth in his ear. “Oh, I guess I was wrong,” you think. Next a man in a business suit walks by talking to himself. “Definitely on his bluetooth,” you say. He turns his head and starts running towards you slinging bird feces, chewing his business cards, and screaming that he has gonorrhea. Nope. You were wrong again. Crazy.
