My dad says, The Fall Guy, Greatest American Hero, and Rocky and Bullwinkle. He also named another, which I forget now, I'll have to ask him again.. something about an astronaut on the moon, termites that had loud boot shuffling walks, and something with two 'F's' in the name, so when they said it they had to say "-F...F!"
I know that sounds vague. He said it might have been just an east coast thing. He actually saw the guy in a local parade back in Massachusetts.
