The Old Jewish Man (sometimes called the Crazy Guy or Crazy Old Man) is Grampa Simpson and Jasper Beardsley's friend. His real name has not yet been revealed. In his youth he was an executive at Warner Bros during the making of Casablanca, having tacked on a later suppressed happy ending, with a question mark that left the door open for a sequel, and the It's a Wonderful Life 'killing spree ending'. He observes that the quality of studio management has changed over the years. At the time of the Casablanca blunder, they 'was just dopes in suits. Not like today!' He diplomatically left unstated whether the difference is that studio executives are more intelligent now, or that they no longer wear suits. He once had a brief period of stardom after his act of dancing on a street corner singing 'The Old Gray Mare' with his pants down became a hit on television. (Source: Fandom.com, CC BY-SA)
