In the 2nd quarter of last night's game, Joakim Noah hit the bench. Someone in one of the rows behind the Bulls bench said something to him… because at :33 you can see (quickly) Noah make the wanking gesture to the fan.
Now… it's not a huge deal. Players have done worse. But that's still, technically, an obscene gesture. And that's still, technically, not something David Stern would like.
We'll have to see if Noah gets whacked (pun intended) with a fine or something.
