Mister Ed: The Lost Episode
Never on TV! But shown in schools, libraries, institutions & available free by certain film rental libraries..."Wilbur Gets The Message", was an episode made in cooperation with the U.S. Treasury Department with a Savings Plan/Savings Bond type message. Rare and funny, it's a true curiosity of its time. Look for George O'Hanlon in the cast, most well known as the voice of George Jetson.
