Um, guys?
You know how Q kept saying "these people are stupid"? What if the actual meaning was that they literally are stupid. As in, a piece of their brain removed. Think, lobotomy. Crazy, right? But what about all those black eyes? Lobotomies can be performed through the eye socket, but it gives the patient a black eye.
Most of the black eyes on celebrities are on the right side, but with some of them it is on the left. Like Justin Bieber. Why? Well, it might have to do with the dominant hand of the patient. Yes, Justin Bieber is left hand dominant.
Matching up left handed celebrities with left black eyes might give some credence to this theory.
