The explanation he gives for his nickname is: "When I was brought home from the hospital as a brand new baby, March 1960, everyone was calling me 'Chrissy', like people do with newborns. You add an 'e' or 'y' or whatever to their name as an instant nickname. Okay, so my brother Joe was three years old, and he couldn't say 'Chrissy', and kept saying 'Kippy'. My brother Dan, who was ten, thought that was hilarious, and from that day on, literally my first day at home, I was dubbed Kippy, never to be called Christopher again except by doctors, teachers, cops, and my mom if she was mad at me."
