Every year, Fred and Ethel would spend a day at the State Fair. Every year, Fred would say, "Ethel, I'd like to ride in that airplane."

And every year, Ethel would say, "I know, Fred, but that airplane ride cost ten dollars, and ten dollars is ten dollars."

One year, while they were at the fair, Fred said, "Ethel, I'm 74 years old. If I don't have a ride in that airplane this year, I may never get another chance."

"Fred, that airplane ride cost ten dollars, and ten dollars is ten dollars," Ethel replied.

The pilot happened to overhear them and said, "Listen folks, I'll make you a deal. I'll take you both up for a ride. If you can stay quiet for the entire ride and not say a word, I won't charge you anything. But, if you say one word, then you'll have to pay the ten dollars."

Fred and Ethel agreed, so up they went. The pilot did all kinds of rolls and dives, twists and turns, but not a word was heard.

He did all his fancy maneuvers again, but still not a word. When they finally landed, the pilot turned to Fred and said, "Gosh, I did everything I could think of to get you to yell out, and yet you never said a word."

"Well," Fred replied, "I was going to say something when Ethel fell out, but ten dollars is ten dollars."
