I've seen this picture floating around the intertubes, and most recently my friend, David sent it on.
I don't understand the cluelessness of this guy, although sometimes the best humor is found where someone has no idea what he's doing, but plunges blindly ahead regardless of the outcome. I have found myself in that condition in various situations.
I can't imagine what this guy was thinking, but I can laugh at his plight. And yeah, the sticker on the back glass of the pickup says OBAMA, although I've never seen a sticker like that. I suspect this photo has been photoshopped.
