Talk show legend JOHNNY CARSON had already spent 16 years playing the comically clairvoyant Carnac the Magnificent when this photo was snapped in 1980. Johnny would don an outrageous red turban and hold an unopened envelope to his head so that he could psychically answer the question within. He’d announce the punchline in a deadpan manner, and then rip open the envelope to reveal the question and crack up his audience. If a joke bombed, Carnac went after the audience with all kinds of creative curses — including, “May the Shah of Iran seek refuge under your sister’s skirt!”
