Man, you kind of have to feel bad for Pau Gasol. It's just not his night. He's been dunked on by Blake Griffin twice, each of which involved Gasol being put on a poster. And after the second one, the look on Andrew Bynum's face pretty much summed everything up.
That's the "yeeeeeeeeouch" face. Probably glad it wasn't him.
Notice the man in the pinkish shirt in the background and the gasps of the crowd.
