I laughed and asked him to do it again; it was a good one. I thought I might like to try it myself, just as 15 years earlier I had stood in front of the mirror in my dad’s hallway for hours, pushing my worm of a left arm out at the reflection, wishing mightily that I could replicate Ali’s cobra jab. And I had found an old cotton laundry bag, filled it with socks and rags and hung it from a ceiling beam in the basement. I pulled on a pair of my dad’s old brown cotton work gloves and pushed my left hand into that 20-pound marshmallow 200, 300, 500 times a day: concentrating on speed: dazzling, crackling speed, in pursuit of godly speed, trying to whip out punches so fast they’d be invisible to opponents. I got to where I could shoot six to eight crisp shots a second—”Shoe shinin,” Ali called it—and I strove to make my fists move more quickly than thought (like Ali’s), as fast as ionized Minute Rice; and then I’d try to spring up on my toes, as I had watched Ali do: I would try to fly like Ali, bounding away from the bag and to my left.
