Crying on the Inside

To be sure, it was in a quasi-meaningless game, but I'd sure like to know what was up with Tim Duncan getting a second technical foul (and thus kicked out of the game) for what looked for all the world to be no greater crime than simply laughing while sitting on the bench. Consider that Duncan's reputation consists of equal parts boringess and good citizenship, it seems especially bizarre that he of all superstars would be treated in this manner. At this point in NBA history, the Spurs have become tedious, but they surely don't deserve to be losing the big rivalry games in this manner.
