The characters I most remember include:
- Mr. Moose, whose riddles and knock-knock jokes invariably ended with hundreds of ping-pong balls cascading from above and hitting the Captain on the head.
- Bunny, who always tricked the Captain into giving him carrots.
- Mr. Green Jeans
- Dennis the Apprentice
- Bill Cosby, he did the Picture Pages educational segments
- Slim Goodbody, a man wearing a bodystocking which showed the internal organs of the human body painted on it in their appropriate locations.
