Old couple at the carnival

An elderly couple John, and Janice go to the carnvail where John spots a helicopter ride.

He runs over and says to his wife "Janice I've always wanted to go on a helicopter ride and look its only ten dollars".

Janice then says "John why would we pay money to go on a ride ten dollars is ten dollars". They end up not riding and finish up walking around the carnival until they go home.

A year later when the carnival comes back they go again and John sees the helicopter ride again and runs over to it.

He says to Janice "honey I've wanted to go on this helicopter ride for a while now can we just go"?

Janice says to him "John I'll tell you the same I told you last year, ten dollars is ten dollars".

This happens a few more years until the pilot is tired of them bickering about it and comes up with a solution.

He says to John and Janice "I'll take you both up for free but the catch is, if anyone of you talk I'll charge ten dollars".

Satisfied with the compromise Janice agrees, so they go up and the pilot is trying every maneuver possible to try to get them to scream or talk, but without fail neither talk.

When they land the pilot sees Janice is no longer in the helicopter and asks John "what happened to Janice"? John then exclaims "she fell out about 5 minutes into the ride ". "well why didn't you say anything"? Asks the pilot.

And without missing a beat John says "well ten dollars is ten dollars".
