MIAMI -- Ray Allen tried to greet his former teammates late in the first quarter Tuesday when he walked to the Celtics bench before entering the game. But one Celtic wasn't in a gracious mood as Kevin Garnett ignored Allen's offer of a handshake, the video immediately becoming viral on YouTube.

Garnett was asked why he passed on greeting Allen: "You know what man, I was just trying to stay as neutral as I could but obviously I'm an intense person. Other than that it was blank, I just saw the Heat uniforms and obviously he's on the other side and I just tried to play the game, man."
