I saw Clint Howard's guest appearance on The Patty Duke Show today. He is Ron's little brother, did Clint guest star on The Andy Griffith Show or Happy Days?

Yeah, he was in 5 episodes of The Andy Griffith Show and he was in 2 episodes of Happy Days.

on TAGS he played a kid named Leon who was always wearing a cowboy suit and eating an apple, and would never talk

He also played on Gentle Ben tv show with Dennis Weaver

He was such a cutie when he was a kid.

Gentle Ben is out on DVD now. A great show.

Or a peanut butter & jelly sandwich...!

The '60s movie Gentile Giant was shown recently on "Movies!" -- with Dennis Weaver and Clint. That led to Clint's TV series Gentle Ben...! Nice show set in the Florida everglades.
