Not sure if it actually happened, but it sure sounded like the Voice of the Celtics, Eddie Palladino, was mocking John Mason last night.
It was in the second quarter and the Celtics had fallen behind by 6 and then made their comeback. Ray Allen sealed the surge back with a three pointer to make it 44-42 and the game went to a timeout.
As Palladino was announcing the timeout after the crowd went nuts he announced it by saying "Timeout Deeeeeeeetroit".
I couldn't help but laugh. That a way to start a rivalry, huh. Have the PA announcers start making fun of each other. I guess Eddie taught that Mickety-mack-mack-heart-attack John Mason a thing or two.

Classic Boston sports arrogance. I sooooooo love being a Celtic fan!!!
(BTW, I think that's what I heard can anyone please confirm this)
