Golf has seen all sorts of weird rulings throughout the years, and Paul Casey was nearly involved in one on Friday at the European Open.
Casey was called in to take a second look at one of the putts he made on during his second-round 73, after it was determined it rolled directly over a bug before diving into the left edge of the hole.
As Casey explains in the video tweeted out by the European Tour, if you knowingly hit an animal - including a bug - while taking a stroke, you have to replay the shot.
