Tommy and Ray were approaching the first tee.
Ray goes into his golf bag to get a ball and says to his friend, "Hey, why don't you try this ball."
He draws a green golf ball out of his bag and says "You can't lose it."
Tommy replies, "What do you mean you can't lose it?"
Ray replies, "I'm serious, you can't lose it. If you hit it into the woods, it makes a beeping sound. If you hit it into the water it produces bubbles, and if you hit it on the fairway, smoke comes up in order for you to find it."
Obviously, Tommy doesn't believe him, but Ray shows him all the possibilities until he is convinced.
Tommy says, "Wow! That's incredible! Where did you get that ball!"
Ray replies, "I found it."
