Muhammad Ali
“I worked at a magic shop in my twenties, and one day Muhammad Ali came in. My boss (a huge Ali fan from back in the day) was visibly in awe. Ali hung around for a couple of hours — we did some magic tricks for him, he did some for us, and he was beyond cool taking pictures with us. He sent us a ‘thank you’ post card a week later and signed it: ‘Cassius Clay — oops, I mean Muhammad Ali.'”
