Shaq Demands Answers -- Who Farted on Miami Heat Bench?!?

Several members of the Miami Heat were attacked last night ... and the culprit was a real butthole ... this according to Shaquille O'Neal.

After the Heat dominated the Chicago Bulls ... Shaq appeared on the post-game show on TNT and pointed out a key moment in the 1st quarter .... when a bunch of the Heat guys were seen desperately trying to plug their noses.

Shaq noted, "This is something you can't do on the bench ... somebody farted ... who farted on the bench??"

Ever the observationalist, Shaq explained ... "The fart goes 4-deep ... the fart goes 4-deep."
