Anyone who lived in New York in the 70's and watched T.V. will probably remember Jerome Mackey. He was a pioneer of the Dojo chain business concept.
His commercials usually featured him standing with a child and saying "Hi, I'm Jerome Mackey and this is Scooter. He is the wrong person to attack." Short demo clips usually followed.
He also appeared on Wonderama.
Seems he was also a musician and an actor for T.V. commercials, not to mention one hell of a businessman.
I don't know anything about his MA background or the quality of his schools, but I have always wondered what he's been up to.
