Here's a good reason why you should not stand in front of a professional golfer, right in the way of his shot.
A fan found this out the hard way at a recent golf tournament.
American professional golfer Bud Cauley hit a good shot during the contest.
However, the ball went hurtling right at a fan standing in the direction of the swing.
The golfer later apologised to the fan through twitter.
The fan also responded to say that though his hand was just bruised, and that there were no broken bones.
