I used to watch Soupy as an adult. It was more than a TV show for children. There was a lot of 'hidden' adult humor. The characters of White Fang, Black Tooth and Pookie were great. He was way ahead of his time.
I watched him on television when I was a child, and once encountered him in person on the street in New York City. I was probably about five. I cannot believe he was so old. I would have figured he might be forty by now, not in his eighties.
