RIP Lennie 'Pufnstuf' Weinrib

So he was the voice, but not the guy in the suit, right?

“Can’t do a little, 'cause you can’t do enough.”

I remember him from his two Dick Van Dyke Show appearances, mentioned in the article.

From the OP link:

No disrespect intended to the man or his talent, maybe he just didn’t get the breaks; but if I were an actor I would live in fear of something like those being the most notable achievements mentioned in my obituary.
