CHICAGO—Shortly after announcing his retirement, heavyweight champion Lennox Lewis, 38, said Monday that he hopes to continue to make money punching things. "I have a few other skills, but I'm probably best at punching," Lewis said. "Cows, computers, sheets of glass—if the price is right, I'll punch it good. I may be retired, but I'm still a powerful good puncher." Lewis added that he would also be willing to hire himself out by the hour for displays of fancy footwork.
