Riddle

John C (top left): Dave, here’s something from one bowls coach to another.

Dave H (top right): OK John, lay it on me.

John C: What is that which comes with a coach, goes with a coach, is of no use whatever to the coach, and yet the coach can’t go without it?

Dave H: You’ve stumped me there John. OK, what’s the answer?

John C: Noise.
