Teed off with 4 other guys on the 116th hoe of a 117 hole weekend golf outing. I had got a 7 on a par 5 the hole before. After looking all around, one guy looks in the hole and sees a Titleist ProV1 in the hole and thinks it is his. We all congratulated him and everyone found their ball but I ended up with a ball short of the green. I looked at it and it was a ProV1 392. I was hitting a ProV1 X-out. I asked him to show me the ball that was in the hole and it said X-out on it. The hole in one ended up being my ball in the hole.
