That's Biden, on the left, with his back to the camera, talking to Breyer and Roberts. The charming Roberts looks charmed by the gasbag VP, while Breyer — though more liberal than Roberts — looks like he's sleeping on his feet.
The short hulk by himself with his back to the camera is Scalia. Also alone, lurking in the background, is the newest Justice, Sonia Sotomayor. Or is Ruth Bader Ginsburg back there too (in the ladies section?) out of camera range?
Brooding over on the extreme right are Justice Thomas and Alito.
In the center, there's the President. As Stevens looks on, Obama laughs at Justice Kennedy's vain effort to enlist the Prez in a game of pattycake. Oh! Pattycake! Such fun!
IN THE COMMENTS: Freeman Hunt says:
Imagine holding a party. Your spouse takes pictures. When the guests leave, you say, "I'll email a group picture to you all."
The guests check their email accounts the next morning to find a picture wherein all of them have their backs to the camera or are by some other means obscured. Except you. You stand, fully visible, smiling broadly, center frame.
He he he.
