If you've got the nerve to heckle a Ryder Cup player over a missed putt, you'd better be good enough to show him how it's done.
Particularly when there's $100 up for grabs.
Let's let Open champion and European stalwart Henrik Stenson, who was partnering Justin Rose in a practice match, take up the story...
"We played a match against Andy Sullivan and Rory McIlroy and they had a putt and Andy didn't make it, and they tried again to get the right line.
"Someone in the crowd yelled 'I could have made that', so we let him have a go."
"Justin Rose put $100 down and the guy drilled it in the centre.
"He would have been chipping if it didn't go in, but all credit to him for making it."
Rose added: "I thought [the money] might make it a bit more real for him, but clearly not. The boys were cupping out, missing it low and this guy just ripped it into the middle. Fair play to him and he celebrated in style.
"It's fun," laughed Rose. "We are doing what we should be doing out here, having fun. We are preparing, we are focusing, but you have to enjoy it."
So who was the heckler-turned-hero?
It was David Johnson, from North Dakota, who later admitted: "I closed my eyes, hit the putt and it happened to go in."
