A boat on the river backfired just as golfer Zach Johnson was about to putt his ball at the PGA Championship. 

As quiet as golf courses are, this must have been REALLY scary. As you can see in the video, the golfer was taken by surprise, and nearly leap out of his cleats.

I'm sure it took a minute or two for Johnson to gather himself after this mishap. Luckily, we didn't see him have to run the nearest restroom---if you know what I mean.

If this backfire was intentional, "not cool."
