I was playing golf the other day when I bumped into my mate. "Look what I've got!" he explained showing me a golf ball.
"What's so special about that?" I asked him
"This ball cannot be lost," He told me. When you hit it into bushes it emits a bleeping sound. When it goes into water a little flag is raised, and if you lose it at night it lights up!"
"That's great! Where did you get it?"
