Help me identify old sci fi show

[Man in the Funny Hat]

My younger brothes and I went to a car show where Twiki was an attraction. They were very disillusioned to discover that his hands were made of spray-painted wood. Still, points to them for having an actor inside playing the occassional recording of Twiki's voice.

The voice, of course, of Mel Blanc, "Man of 1000 Voices," including Bugs Bunny, Daffy Duck, Porky Pig, Sylvester the Cat, Tweety Bird, Foghorn Leghorn, Yosemite Sam, Wile E. Coyote, Barney Rubble, Mr. Spacely, and more.

Just felt that bit of trivia needed to be aired, though we all knew that already.
