Sam and Edna go to the state fair. There is a guy selling rides in a helicopter for $50 per person. Sam turns to Edna and says, "I've always wanted a helicopter ride!" Edna's response, "Sam, we can't afford it. We are not rich people. Fifty bucks is fifty bucks!"
They come back the following year. The pilot and his helicopter is there again. Sam again tells Edna he wants to take a ride. Edna's answer is the same. "No, Sam. Fifty bucks is fifty bucks."
Ten years go by. Same fair. Same pilot with his helicopter. Same conversation every year. "Fifty bucks is fifty bucks." But this time Sam won't be dissuaded. "Edna," he says, I'm 80 years old. I don't know how much time I have left. If I don't take that ride now, I might never be able to." The pilot, overhearing them, says, "I'll make you a deal. I'll take you both up. If you are quiet the entire ride, it will be free. But if either of you calls out, I'll charge you." Finally, Edna agrees, and up they go.
The pilot decides to give them a heck of a ride. Steep turns, turns, climbs and descents on the edge or aerobatics. Nothing. Not a peep out of either Sam or Edna. Complete silence. Landing, he says, "I'm really impressed. I tried everything. though for sure you'd start yelling."
Sam replies, "Well, I almost said something when Edna fell out, but, you know. Fifty bucks is fifty bucks!"
