A farmer and his wife went to a fair. The farmer was fascinated by the helicopter rides, but he balked at the $25 tickets.

"Let's make a deal," said the pilot. "If you and your wife can ride without making a single sound, I won't charge you anything. Otherwise you pay the twenty-five dollars."

"Good deal!" said the farmer.

So they went for a ride. When they got back the pilot said, "If I hadn't been there, I never would have believed it You never made a sound!"

"It wasn't easy, either," said the farmer. "I almost yelled when my wife fell out"
