If you're a fan looking to pull off a practical joke during a PGA Tour event, make sure Rory McIlroy isn't around to interrupt it.
Per Adam Schupak of GolfWeek, a fan walked onto the course during the third round at the BMW Championship on Saturday with a remote control golf ball and dropped it on the 15th-hole green in an attempt to get it to go into the cup.
After a few seconds of trying to keep the ball from going into the hole, McIlroy just picked it up and threw it into the pond at the front of the green.
