Everybody loves a fun round of Putt-Putt miniature golf.

It's as American as apple pie. Pretty much every kid had or attended a mini-golf birthday party at some point in their adolescence.

But at some point, kids typically grow out of it and the only time you see an adult playing mini golf is when they're playing with their kids.

And then there's these guys.

You might be surprised to know that there are professional mini-golf players.

They're grown men that practice mini-golf for hours and hours. There are even tournaments!

Check out the video below which documents one of those professionals on his quest for the perfect putt-putt performance.
