I was 5 years-old and my father was the President of Crayola Crayons. This gave me significant popularity points as a kindergartner. One day, my parents came home to find that I had taken my Crayola markers and painted all over all of the white walls in the house. As protocol for this type of normal occurrence, my mother scolded me while my father, as a marketer of ideas, stood back and thought. It was in this precise moment that the washable marker was invented. I take some credit for this invention.
