Undisputed Truth by Mike Tyson with Larry Sloman:
My brother Rodney was five years older than I was so we didn’t have much in common. He’s a weird dude. We’re black guys from the ghetto and he was like a scientist—he had all these test tubes, was always experimenting. He even had coin collections. I was, like, “White people do this stuff.”
He once went to the chemistry lab at Pratt Institute, a nearby college, and got some chemicals to do an experiment. A few days later when he went out, I snuck into his room, started adding water to his test tubes, and I blew out the whole back window and started a fire in his room. He had to put a lock on his door after that.
I fought with him a lot, but it was just typical brother stuff. Except for the day that I cut him with a razor. He had beaten me up for some reason and then he had gone to sleep. My sister, Denise, and I were watching one of those doctor-type soap operas and they were doing an operation. “We could do that and Rodney could be the patient. I can be the doctor and you can be the nurse,” I told my sister. So we rolled up his sleeve and got to work on his left am. “Scalpel,” I said, and my sister handed me a razor. I cut him a bit and he started bleeding. “We need the alcohol, nurse,” I said, and she passed it to me and I poured it onto his cuts. He woke up screaming and yelling and chased us around the house. I hid behind my mom. He still has those slices to this day.
