Clooney's wrap-day prank to get even with Brad

George Clooney got his own back on Brad Pitt for making him look like a egomaniac on the set of Ocean's Twelve - by making him drive through rush-hour traffic with a sign suggesting he was lacking in manhood.

Clooney wasn't happy when he realised he'd been referred to as Mr Ocean on the set of the film in Italy for a full month because Pitt sent a memo to all crew insisting they call him by his character's name.
