Ozzy Osbourne is in commercials again, this time for the Samsung Jack personal assistant handset. In typical Ozzy style we dont understand a word the aging rock star is saying but its Ozzy and we love him. In the spot, Ozzy makes funny jokes about how the phone is more attuned to his personal needs than his own assistants, which he claims had hearing problems and kept really odd hours.
