Here's a link to a good article about the Half-Wit, as Ban Jones called him. This part made me laugh:
"The chestnut colt with the flying tail began his racing career on June 3, 1940 with a narrow victory in Chicago under Jack Richard. He was far superior to the rest of the field, as evidenced by the fact that he covered virtually every inch of the track, with special attention given the outside rail, while the rest of the youngsters ran a straight line."
