Zach Johnson Gets A Little Scared At Fan Prank

By David Heim 

Zach Johnson was in the midst of a pretty solid day at the John Deere Classic Sunday--tied for third to be exact. But then, this happened on the 16th green.

After what turned out to be an air cannon on a boat, set off by a fan, Johnson literally jumped. There is nothing cool about being distracted in the middle of your back swing. If it was an accident, okay, move on. But if not, that's totally not cool man. Not only does this prank scare the golfer, but it alarms the fans as well. Who even has an air cannon?
