This is really something else. Apparently there's an alpha male monkey in a zoo somewhere that really has it out for people who turn their backs to him. Is it the shirt? Is it the baseball cap? Why does he do this? This guy was "attacked" (with a glass barrier), and then a year later, returns to the same place, and was "attacked" again by the same monkey. I wonder why he did this. Do you know?

Why do you think the monkey did this? Does he do it to everyone?
