Happy Birthday Muhammad Ali

Muhammad Ali (born Cassius Marcellus Clay Jr. on January 17, 1942) is a retired American boxer and former three-time World Heavyweight Champion. To date, he remains the only man to have won the linear heavyweight championship three times (the linear title is recognized by tracing an - almost - unbroken lineage of titleholders going back over 100 years, with nearly every champion defeating the previous titleholder in the ring). Ali was also the winner of an Olympic Light-heavyweight gold medal. In 1999, Ali was crowned "Sportsman of the Century" by Sports Illustrated and the BBC.
