After a blistering start on Thursday, Rory McIlroy followed it with a disastrous second round in the ongoing BMW Championship. However, he was still a major talking point due to a rare moment he was involved in.On Friday, sometime during the second round, McIlroy stopped to hit a shot to save a bug sitting on his ball. He moved the bug with his tee pin and could have possibly moved the ball.The PGA Tour shared the video on Twitter, where fans jumped into the comment section to crack jokes about what if Rory McIlroy would have moved the ball. One fan wrote,"That’s 2 strokes…"One guy's comment was probably one of the funniest as he wrote that it should be against the rule and the golfer must have hit the ball into the 'stratosphere' (or in the sky) with the bug sitting on it. The comment read:"Should be against the rules you should be required to send that bug into the stratosphere"Another fan jokingly questioned how far the ant would have gone if the golfer would have hit the shot.A fan humorously wrote agreeing that an ant should not be executed on National Television.Here are some funniest comments from fans on Twitter:Where does Rory McIlroy stand on the BMW Championship leaderboard?The Northern Irish golfer entered the Olympia Fields North Course in the third rank in the FedEx Cup rankings.
