A guy and his buddy went golfing... and one noticed the other only brought one ball. Guy 1: ""Hey, what are you going to do if you lose that ball?"" Guy 2: ""Well, it happens that this ball is impossible to lose."" Guy 1: ""Impossible to lose? What if you hit it in the water?"" Guy 2: ""The ball floats."" Guy 1: ""Ok, but what about when it gets pitch black and you hit it in the rough?"" Guy 2: ""No problem, it glows in the dark."" Guy 1: ""Wow, that's really cool! Where can I buy one?"" Guy 2: ""Not sure, I found this one.""
