T-shirts pulled behind the head

Ever since I was a young man, I have enjoyed the sight of a guy who has pulled the front of his t-shirt up and over his head but still has his arms in the sleeves.  It creates that same great diagonal separation of arms from chest that I love from back packs.  Plus, it has that air of the forbidden to me because it's showing off their chest AND it was something my mother always yelled at me for doing. She claimed it would stretch out my shirts.  So here's to the guys who didn't care if they stretched their shirts and were more than willing to show off their great bodies for the rest of us to enjoy.
