Johnson teed up his ball, squared up his stance and took a practice swing.
Johnson said after the round when told video of the swing existed.
He was then informed that because the contact he made was unintentional, it did not count as a penalty stroke. "I thought I'd done it all, but now I know I have", said the 43-year-old, who added Kuchar would not let him forget the gaffe.
You can watch the hilarious scene play out below. There was a misplaced rain jacket, a friendly discussion with rules officials, a turtle, a security guard's lap (or back) and a smacked marker on a tee box that became a huge hit on social media.
Only Johnson's pride was hurt because he was allowed to re-tee the ball without penalty because he had not meant to move it.
The most impressive part of the sequence is that Johnson then stepped up and bombed a flawless drive down the middle of the fairway.
Further, if anyone doubted the intent of his swing, his immediate exclamation of "Oh s--!" made it pretty clear that it was an accident.
The good news for Johnson: He hit his actual drive 285 yards down the middle of the fairway, knocked his second shot to 30 feet and two-putted for birdie on the 510-yard, par-5 hole.
