Clooney was accompanied by girlfriend Sarah Larson, and was so P.O.'d by the aggressive paps -- he pulled over to lash out at some who he said were cutting off other vehicles to get a good shot of him. George is a little touchy -- and who can blame him? He and Larson were involved in a New Jersey crash in September when they were hit while riding a motorcycle -- leaving George banged up and Sarah with a busted ankle.

Even when he's upset -- he's hot.
