Michael Bay -- Attacked by Crazy Man Wielding Air Conditioner

Famed director Michael Bay almost got clobbered by what appears to be a drugged out crazy who swung an air conditioner at his head on the set of "Transformers 4."

The incident occurred today in Hong Kong. The attacker somehow made it on the set, accosted several members and then set his sights on Bay. When Bay realized what was up, he saw the crazy man swinging an air conditioner right at his noggin.

Bay then wrestled the unit out of the attacker's hands and security quickly subdued him.
