He also won the Indianapolis 500 three times. Yes, three:
Jason Matthews. This is a guy I’d never heard of, but am now intrigued by. He was a former CIA officer who wrote three spy novels (affiliate link) that are highly praised for their realism.
Johnny Crawford. He was one of the original Mouseketeers, and later played Mark McCain, son of Lucas McCain, on “The Rifleman”.
Billie Hayes. Yes, “Witchiepoo”, but also “Mammy Yokum” in “Li’l Abner” (she replaced Charlotte Rae on Broadway, and played the role in the 1959 film version and the 1971 TV movie version).
