Took us 3 hours to play 12 holes because the FIVEsome ahead of us were the slowest group in history. Arrived at the 146 yard par 3 13th and watched the group ahead hit 10 balls off the tee with no Marshall in sight. I would usually hit my 150 club hear to ensure I cover the water but given I was irate at the pace of play, I decided to step on a 7 iron and flushed it. As soon as it left the club I yelled "get in the f***king hole. It was dead on line the entire way, hit the green about 10 feet behind the pin and rolled straight in. A gentleman on his porch beside the green started screaming and hollering and I knew it was in.
