SEAN PENN'S BIG TIP

TIP OVER!

Sean Penn -- groggy after months directing his smash-hit "The Pledge" -- exited trendy Cyrano's in Hollywood and handed the parking kid what he thought was a $2 tip. "WOW, thank you, Mr. Penn!" gushed the guy. That's when it dawned on Sean that he'd handed over two $100 bills. He snatched them back from the guy, apologized -- and forked over two $1 bills. (Moral: Never say WOW! It's a tip-off!)
