Brad pranks Clooney with diva demands list

George Clooney got a taste of his own practical joking on the set of Ocean's Twelve in Italy when pal Brad Pitt turned the movie star into a diva with a simple memo.

Clooney, who is famous for pulling pranks on his co-stars, spent two weeks on the set scratching his head and trying to figure out why his crew insisted on calling him by his character's name in the film, Danny Ocean.
