Muhammad Ali once dodged 21 punches in 10 seconds

During a fight against Michael Dokes in 1977, legendary boxer Muhammad Ali showed exactly what he meant by 'float like a butterfly'.

Fighting a man 16 years his junior (Ali was 35 and Dokes was 19), Ali was pinned against the ropes when he put on a display of incredible skill.

Over the course of 10 seconds, Ali dodged an astounding 21 punches before taunting Dokes with a cheeky little dance.

It was the kind of sheer prowess that made Ali so phenomenal. He didn't have a particularly strong punch, but his ability to dance through his opponent's attacks was ridiculous.

He had so many great moments that it's hard to say if this was his best, but it certainly was an incredible sight.
