50 $

Morris  and his wife Esther went to the state fair every year, and every year  Morris would say, 'Esther,I'd like to ride in that  helicopter.' Esther  always replied, 'I know Morris, but that helicopter ride is fifty  dollars, and fifty dollars is fifty dollars'
One  year Esther and Morris went to the fair, and Morris said, 'Esther, I'm  85 years old. If I don't ride that helicopter, I might never get  another chance.' To  this, Esther replied, 'Morris that helicopter ride is fifty dollars,  and fifty dollars is fifty dollars.'
The  pilot overheard the couple and said, 'Folks I'll make you a deal. I'll  take the both of you for a ride. If you can stay quiet for the entire  ride and not say a word, I won't charge you! But if you say one word,  it's fifty dollars.' Morris  and Esther agreed and up they went.
The pilot did all kinds of fancy stunts, but not a word was heard... He did his daredevil tricks over  and over again, but still not a word.
When  they landed, the pilot turned to Morris and said, 'By golly, I did  everything I could to get you to yell out, but you didn't. I'm  impressed!'
Morris  replied, 'Well, to tell you the truth, I almost said something when  Esther fell out, but you know, fifty dollars is fifty  dollars!'
