I really should browse through Muppet Wiki more often.
I knew from reading Brian Jay Jones's book that Jim's pitch for MOKI was passed on, including one potential director who told Bernie Brillstein that he recognized Jim's visual mind, but the story scared the bejeezus out of him... but I didn't know, until looking at Muppet Wiki, that said director was Howard Morris, a.k.a. Ernest T. Bass from THE ANDY GRIFFITH SHOW, and the voice of Flem from COW AND CHICKEN.
