It never really existed. It was a follow on from a drunk night. Probably in someones cupboard. Now internet attributed to Mr. Rogers even though it's really Arthur Greenwald and Barry Head's work. Which since they wrote Mr Rodger's I guess it is the entity that's Mr Rogers, but never published under that entity, so not really. The Good Neighbor: The Life and Work of Fred Rogers - "In 1977, while on a break, Arthur Greenwald and fellow writer Barry Head cracked open a bottle of Scotch, and to blow off steam, coined the term “Freddish” to describe the grammatical rules in writing for Fred Rogers. Head and Greenwald, also a talented cartoonist, even created an illustrated manual called “Let’s Talk About Freddish,” a loving parody of the demanding process of getting all the words just right for Rogers.12 12.
