I am a true Legend and an All Time Great of the rings; During my career I was a true sensation with my attacking non-stop punching style. That helped me to attract huge crowds to my fights, making me a resident in the Mecca of Boxing; It was a Golf Champion and it's friends that helped me to start my career in boxing. They were convinced by my quality after they watched me fight in authentic "battle royals" where I faced 5 men in the ring at the same time while all men - including me - were blindfolded. The last men standing wins, and I rarely lost; I fought a total of 33 times against Champions of the World and Hall of Famers; I was Champion of the World in my division, not once but twice; In one year alone, I beaten 3 HOF's 4 times; Amongst the tough fighters that I faced and beat, there's Johnny Bratton, Tony Janiro, Tippy Larkin, Carmine Fatta, Tuzo Português and the tough Lulu Constantino; After I ended my career, I managed a shoeshine concession in Miami. Muhammad Ali stopped there everyday when he was in town and always gave me a 100€ tip for a shine; I was born on April Fool's Day; Who am I?
