Ron Artest throws Ariza's shoe in the stands

I don't know what's funnier? Artest picking up and throwing Ariza's shoes or the look that Ariza gives Ron.
If the refs would of seen that could it possibly be a delay of game or a technical. If you hold a player to prevent them from playing or throw the ball in a direction that a player must go out of his way to get then it's one of the above. The argument against that would be it's not necessary to have your shoes to play.

"how about that sportsmanship?"
