Jose Canseco twitches exactly the same way.
Why is he so twitchy? Is it because of steroids or what?
I wondered this at first. Now I'm actually thinking Tourette's because I have never seen anyone twitch so much. When it's not his face, he's twtiching his neck and popping his shoulders. Weird.
I don't know if it has anything to do with the long term use of steroids to increase fast-twitch muscle fibers, but it seems a strange coincidence. I do know that many anabolic steroid users report odd twitching in various muscles, so IMO it walks like a duck and quacks like one, too.
