My World... And Welcome to It with Henry Morgan and Ray Walston (1969)

This rare sitcom had a serious cult following when it aired for one season in 1969-70. Based on "drawings, stories, inspirational pieces and things that go bump in the night" by James Thurber, it featured a lead character scared by real life, who retreated into his drawing board. Sounds sort of like me, except my drawing board is old TV shows on the internet. After NBC got rid of the show, CBS bought it and aired it from May 1972 until September.
