A farmer and his wife went to a fair. The farmer was fascinated by the airplane rides, but he balked at the ten-dollar 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 ten 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."
