"That's too much." said the farmer.
The pilot thought for a second and then said, "I'll make you a deal. If you and your wife ride for 3 minutes without uttering a sound then the ride will be free. But if you make a sound you'll have to pay $10."
The farmer and his wife agreed and went for a wild ride. After they landed the pilot said to the farmer, "I want to congratulate you for not making a sound. You are a brave man."
"Maybe so," said the farmer, "but I gotta tell ya, I almost screamed when my wife fell out."
