As mentioned previously, here is everything you'd want to know about The Soupy Sales Show--because you asked for it! Well actually, no one asked for it, but I'm giving it to you anyway.
Soupy was a nightclub comedian and radio host in various places, but he got his break hosting local and national versions of his children's TV show. The original ran throughout the 60s and was revived briefly in the late 70s (which is the version that I grew up with). Although aimed at children on the surface, the show clearly had an adult sense of self-awareness (note the frequent and uninhibited laughter from stagehands in several clips).
The following links will provide his story more clearly:

Finally, here is Soupy in a commercial for the famed Gino's resaurants (Gino's--hmm. That could be a post in and of itself).
