Bill and Ralph were approaching the first tee. Ralph 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. "You can't lose it."
Bill replies, "What do you mean you can't lose it?" Ralph 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, Bill doesn't believe him, but Ralph shows him all the possibilities until he is convinced. Bill says, "Wow! That's incredible! Where did you get that ball!"
Ralph replies, "I found it."
