When you Google Michael Phelps he appears ahead of Michael Collins. Yes, that indicates the measure of the man.
He’s also the most decorated Olympian of all time with 18 swimming golds. In his spare time (which he has more of these days) Phelps golfs.
Here, in this animated GIF, the American holes a 50-yard putt at the Dunhill Links Championship at Kingsbarns in Scotland. More on the story here, but for now enjoy this glorious shot.
