PBS children's show 70's/80's with an Alton Brown doppleganger

There was a show or a segment of a show that had an actor that I recall looking like Alton Brown. There was also at least one actress, possibly two. They were talking about fairy tales I think and acting it out. They would make changes and then type it up on a typewriter. The memory is hazy but strong and I can’t find any information or anyone that remembers anything like it.
Anybody got any ideas?
