Take reigning PGA Tour Player of the Year Justin Thomas.
The 24-year-old came into grief during the second round the Hero World Challenge in the Bahamas when his ball came to rest beside a small rock.
The results weren't pretty.
Thomas flipped his club around and, attempting to hit the ball with the back of his clubhead, took a swipe at his ball left-handed and missed the ball, collecting the rock instead.
The slow motion replay shows his ball only moved once the rock had been displaced.
It was a moment to forget for last year's PGA champion who finished with a respectable round of 70 to be 5 under after 36 holes and seven shots behind leader Charley Hoffman.
