I can to raise my left eyebrow a bit, but as I wear glasses it's usually a pointless exercise as no one can see my party trick.
Edit: If I take my glasses off I walk into walls, so it's not worth it.
But that that will go over big at parties too. Do it!
While I appreciate I'd be providing great free entertainment, the trip to the ER isn't worth it.
I know, I'm a spoilsport.
