Martha and her husband Bill went to the state fair every year and every year Martha would say, "Bill, I'd like to ride in that airplane."

Bill always replied, "I know Martha, but that airplane ride costs 10 dollars, and 10 dollars is 10 dollars."

One year Martha and Bill went to the fair and Martha said, "Bill, I'm 81 years old. If I don't ride that airplane I might never get another chance."

Bill replied, "Martha, that airplane ride costs 10 dollars, and 10 dollars is 10 dollars."

The pilot overheard them and said, "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 one word, I won't charge you; but if you say one word it's 10 dollars."

Martha and Bill agreed and up they went.

The pilot did all kinds of twists and turns, rolls and dives, but not a word was heard. He did all his tricks over again, but still not a word.

When they landed, the pilot turned to Martha and said, "By golly, I did everything I could think of to get you to yell out, but you didn't."

Martha replied, "Well, I was gonna say something when Bill fell out, but 10 dollars is 10 dollars."
