I was standing immediately behind them at that exact moment, off to the left of the picture just out of frame. Dr. Bolden is just barely visible.
If memory serves, Dave WAS just popping his finger with his mouth...
No, wait.
He was, as jspatz1 wrote, explaining the game to Dr. Bolden and the young lady in front of him. This was during QF4-1 on Curie, my team was on the field (That's our head coach to the right of Dave wearing the Pi-O-Neers shirt) and I knew who Dr. Bolden was and wanted to stand right there just in case I had a chance to speak with him (taking advantage of a rare opportunity).
The words were "each ball is worth one point..." (That's my story and I'm sticking with it.)
BTW,
Dave's on his bike ride at the moment, too cheap to drive the length of Florida he takes a bicycle...
