Interview with the real Joker

Above, a 1966 interview with the best of all Jokers, the inimitable Cesar Romero who camped it up for the Batman TV series (1966-1968) and subsequent theatrical film. Romero famously refused to shave his trademark mustache for the role so they just slathered the white greasepaint right over his whiskers. (Interview with Romero starts at about 3:36, but watch from the beginning to catch an interview with Julie "Catwoman" Newmar.)
