Don't mess with Texas. Or Joey Crawford.

Minutes before tipoff of Wednesday night's Western Conference Finals Game 2, perpetually grimacing referee Joey Crawford sauntered over to Mavericks guard Nick Van Exel.

"Don't mess with me tonight," Crawford warned. "Because, like Muhammad Ali, I'm a baaaaad man."

And during the Spurs' 119-106 victory, Crawford indeed proved that he is baaaaad, man.
