The Mysterious Man and the Unknown Actor

You may have noticed a man named “Mister Schwamp” who would occasionally appear in random episodes. He was a middle-aged man with dark hair that appeared to be a toupee. He was usually found sitting on a park bench or in crowd scenes. Andy or Barney would acknowledge him with “Hello, Mister Schwamp” at which point he nodded and smiled. He also appeared in two episodes of the spin-off Gomer Pyle, U.S.M.C. To This very day, nobody knows who played Mr. Schwamp.
