Hot Dog was a children's television series that ran for one season (1970) on NBC's Saturday morning. Called "The Show About Stuff," it was basically the network version of the "How do they make _____?" segments from Mister Rogers and Sesame Street, only with groovier music--and commentary from Woody Allen, Joanne Worley, and Jonathan Winters [who replaced Tommy Smothers, who was in the pilot, which has some sweet, hand-drawn titles, btw].
Which is funny, because of course, The 'Street and The Electric Company were both explicitly patterned after Laugh-in, and even used some of the same characters. Lee Mendelson, the guy who had approached Charles Schulz about making an animated TV special once , was the producer of Hot Dog, which was created by Frank Buxton. Here's what Buxton says about the series on IMDb:
Each week the program showed where four or five common everyday items come from and answered kids' questions about them - "Is that really lead in a lead pencil?", "how do they make baseballs?", "What makes popcorn pop?", "Who invented the hot dog?". etc. The "hosts" - Woody Allen, Jonathan Winters and JoAnne Worley would attempt to answer these questions in their own comedic way and then, through imaginative cinematography, editing and music, the actual answer was shown. Winters portrayed many of his characters as "experts", Worley worked hard to give correct answers and Woody Allen (who's only TV series this is) gave bizarre responses, as expectedHot Dog's short segment format made it easy to chop up and syndicate into local TV station Saturday morning schedules, and it was apparently incorporated into Kids Are People, Too! too.
According to TVParty, Hot Dog was sponsored by Howard Johnson's, whose spokesman was Bob McAllister, the last host of Wonderama, the local kids show on New York's WNEW Channel 5. So Hot Dog seems to be straddling two eras: the end of locally produced kids programming and the emergence of national network programming [which, for kids, had been pioneered by Rogers and the Children's Television Workshop.]
Unfortunately, at the moment, there are only two intro/credit clips and three "making of" clips online, so no McAllister. The NBC intro has the cast modeling the sweet-looking Hot Dog logo t-shirts, which seem like prime candidates for revival/knockoff/homage. And then there's this wild credit: "Connie Davis (Almost A Doctor)". Any idea what that's about?
As for the clips, there's the first 80% of making a surfboard; the making of a hot dog bun [unsliced]; and the making of a baseball glove. Still missing: clips of "pencils, crayons, money, toothpaste, etc."

 Am I the only one whose cranky idealism about commercialization, creative "selling out," and idyllic childhood nostalgia got totally thrown out of whack by this paragraph from Lee Mendelson's Wikipedia bio?
While Mendelson was attempting to find a market for the Schulz documentary, he was approached by The Coca-Cola Company, who asked him if he was interested in producing an animated Christmas special for television. Mendelson was, and he immediately contacted Schulz in regards to using the Peanuts characters. Schulz in turn suggested hiring animator and director Bill Melendez, whom Schulz had worked with while creating a Peanuts-themed advertising campaign for the Ford Motor Company. Mendelson also hired jazz composer Vince Guaraldi after hearing a Guaraldi-composed song while driving across the Golden Gate Bridge.
