He guest starred on a few S@S episodes towards the end. He was always in a different role with a different occupation. He must have been popular because every time he says yessssssss the audience applauses. I know I heard his voice on the Flintstones before. Anyone knows who i am talking about?

His name is Frank Nelson.

I was right. I know I heard his voice on the Flintstones.

Frank Nelson was also the voice of Spiffy the Cat in the cartoon series The Oddball Couple.

He was also in episodes of "I Love Lucy." He was the talent scout that signed Ricky to a movie deal, and later became a semi regular as the Ricardo's neighbors when they move to the country.
