Well I have never had any, other than people calling me Getz in school, and later on Gman, but my screen name is my sons nick name. Grunter....when he was young he used to make this grunting sound to get attention. I'm talking 1 1/2 years old. so when I needed a screen name, Grunters Dad, gruntersdad, just seemed natural.
My Father WAS a Rocket Scientist!
