In Willard's 1982 autobiography, "The Joy of Living", he writes about those early days of television, interacting with " ... an innovative bunch of puppets created by a guy named Jim Henson. They were called the Muppets. ... I worked with a bald- headed Muppet with a big nose, named Sam, sort of the way Fran Allison worked on Kukla, Fran and Ollie.  Then there was the frog named Kermit. I used to do a commercial for a local peanut butter called Schindlers. He'd open his mouth, I'd give him a big spoonful, and he'd go 'ahh'".

the "tel-le-vision like this" when the "platter gets stuck".
