Tom Slick was one of two backup features to the original George of the Jungle (1967). In a sense a parody of Japan's Speed Racer, which arrived in America around the same time, Tom (Bill Scott, using a variation of his Dudley Do-Right voice) raced around the world, accompanied by his sweetheart, Marigold (June Foray) and her mother, Gertie (Scott doing a rare female role).

Sad to say, more people remember Super Chicken than they do Tom Slick today. You don't really see t-shirts with Slick's picture, do you?
