Apparently, they play the following video on the jumbotron at The Garden during the fourth quarter of games in which the Celtics are assured of victory. And, apparently, the fans at The Garden go nuts every time the man in the “Gino” t-shirt dances during this clip.

Can’t say that I’m a fan of the Celts — in fact, quite the opposite, given my allegiance to the Pistons — but I must admit that this is a truly bizarre and wonderful victory celebration.
