Purely History on Instagram: "The unscripted magic of Mary Tyler Moore. In 1962, during an episode of The Van Dyke Show, Mary Tyler Moore unexpectedly sank a difficult pool shot in front of the live audience. The plan had been to splice in a professional making the shot, but when Moore made it herself on the first try, they decided to keep it. Her authentic reaction added to the charm and made the scene unforgettable."
