The Ryder Cup hasn't even begun yet and it is already creating some brilliant memorable moments.
Thursday saw the players making their final preparations and getting in the last bit of practice on the Hazeltine course before the event tees off on Friday.
Of course, with this year's edition of the competition taking place in the States, the European players know that they will up against the crowd just as much as their direct opponents.
And Rory McIlroy was given a taste of what to expect during his practice session as he was heckled for struggling with a particular 12-foot putt.
McIlroy then surprised one of the more vocal people in attendance by inviting them to attempt the same putt on the green.
You see what happened in the video below as the American fan, named David Johnson, stepped onto the green to line up the shot.
Justin Rose made it even more interesting by placing a $100 dollar note next to the ball which was Johnson's to claim if he could succeed where McIlroy had struggled.
So what did Johnson do? Nailed the putt straight in the hole at the first time of asking of course.
The watching crowd erupted into the first of many big cheers we should expect over the weekend.
Even McIlroy can be spotted enjoying the shot as he raised a wry smile.
Henrik Stenson, who also watched Johnson's moment of glory, said: "The boys were struggling with their lines and David was kind enough to come down and show us how to do it."
Meanwhile, Europe will be hoping the World No.3 can sort out his putting quickly as McIlroy will undoubtedly have a big role to play in any success the visitors have.
