A day after Paul Pierce mocked LeBron James on Twitter, Heat forward Udonis Haslem questioned the toughness of the Celtics captain.

"It's been a pleasure to bring my talents to south beach," was the message that appeared on Pierce's twitter feed. "(N)ow on to Memphis."

Asked if he had a response to Pierce's tweet, Haslem responded with a question of his own.

"Paul who?" Haslem shot back. "Man, ain't nobody paying them dudes no attention, man. You know what studio gangster is? Look up that, look up the definition of studio gangster. I'm here to play basketball. First of all, I don't tweet. So I wouldn't know what he tweeted if you guys didn't tell me."
