In 1975, John Burstein created the character “Slim Goodbody” the “superhero of health.”
His character began in a hospital to entertain/educate children. He graduated to daily shows, then to Captain Kangaroo, and eventually to his own series, Inside Story.
At 75 years he’s still touring as Slim in a show called Bodyology.
When I was a young child, in the mornings, I would watch Captain Kangaroo on a black and white television. Those are hard to find now days, though I don't think many people are looking 😆. The characters on Captain Kangaroo besides himself were Mr. Green Jeans (who I call Mr. Green Beans just so my wife will correct me), Grandfather Clock, Mr. Moose, and Bunny Rabbit, there were probably more that I don't remember. There was a cartoon that I liked, Tom Terrific who had a funnel shaped thinking cap and a side kick, His side kick was Mighty Manfred the Wonder Dog. Tom could transform himself into anything he wanted to be, via his magic hat. You know, after two or three-hours children's programming would end, and we would go outside. Now a days, there are complete channels of children's entertainment 24 hours a day.
