It was because of my father that from the ages of seven to fifteen, I thought that my name was ‘Jesus Christ’ and my brother, Russell, thought that his name was ‘Dammit’. “Dammit, will you stop all that noise?” And, “Jesus Christ, sit down!” One day, I’m out playing in the rain, and my father yelled, “Dammit will you get back in here!” I said, “Dad, I’m Jesus Christ!”
