Thanks to Digby and Crooks and Liars who pointed this out:

Brian Williams, MSNBC, Wednesday March 5th:

You know what I thought was unsaid —they took their position Chris, we’re seeing the replay — they end up in this spot and the sun is coming is just from the side and there in the shadow is John McCain’s buckled, concave shoulder. It’s a part of his body the suit doesn’t fill out because of his war injuries. Again you wouldn’t spot it unless you knew to look for it. He doesn’t give the same full chested profile as the president standing next to him. Talk about a warrior.

Who needs romance novels? We have a natural writer in Brian Williams. The sun. The battle wounds. The full chest of George W. Bush. Oh my. Where's the codpiece?
