17. Muhammad Ali NEVER Refused To Sign An Autograph During His Whole Career
The old tale goes that Ali's hero, Sugar Ray Robinson, refused to sign an autograph for him when he was young. Never wanting to make anyone succumb to the feeling Robinson bestowed upon him, The Greatest made sure to sign every single autograph and pose for every single picture he was asked for. Something he famously kept up right the way through his career. Even at the height of his mainstream fame. Considering how famous he turned out to be, you can only imagine the number of signatures he gave out reached the millions. Some achievement.
