The internet will not cooperate and provide pictures, but Christopher Judge does this so much better than the rock. It's like his thing.
As for myself, I do not post pictures of myself(because I'm lazy and also ugly) but I am fairly good at it with my left eyebrow. I used to be able to do with my right, just not as well, but now I've lost the skill. I could still do it but I'd need to spend a few hours in front of a mirror reminding my face how to do it, and even then it wouldn't be as good as my left. It's actually a fairly routine facial expression for me, don't really know why.

Always thought it was related to which side you are dominant on.
I can raise my right, but not left and am righthanded. Those who can perform the wave are demons and need jesus.
Imean look at this
I'm a righty and I can only raise my left. It might have to do with which eye is dominant. I'm left eye dominant, though like I said, I could do it with my right, just not as well, and I'd need to practice.
