Has anyone else ever noticed this? He has this way of flipping it backwards over his head to put it on. He does it in everything - all the time when he's Bartlett in the West Wing, and I noticed him do it in Wall Street too (and there's a video on Youtube from when he's young as well). According to IMDB, he has to do it because he has limited lateral movement in his arms thanks to complications at birth. But the thing is, I tried it, and I couldn't for the life of me get it to work.
I want to be more like Martin Sheen.
