Art and his wife Agnes went to the State Fair every year.
Every year Art would say, "Agnes, I'd like to ride in that there airplane."

And every year Agnes would say, "I know Art, but that airplane ride costs ten dollars, and ten dollars is ten dollars."

This one year Art and Agnes went to the fair and Art said, "Agnes, I'm 71 years old. If I don't ride that airplane this year I may never get another chance."

Agnes replied, "Art, that there airplane ride costs ten dollars, and ten dollars is ten dollars."

The pilot overheard them and said, "Folks, I'll make you a deal.
I'll take you both up for a ride, and if you can stay quiet for the entire ride and not say one word, I won't charge you. But if you say one word it's ten dollars! "

Art and Agnes agreed and up they go. The pilot does all kinds of twists and turns, rolls and dives, but not a word is heard.
He does all his tricks over and over again, but still not a word.

They land and the pilot turns to Art, "By golly, I did everything I could think of to get you to yell out, but you didn't."

Art replied, "Well, I was gonna say something when Agnes fell out, but like Agnes always said, ten dollars is ten dollars."

Poor Agnes.
