English translation punch line A3 is not funny and does not need machine translation!

I translated it myself ... maybe some places are not very smooth ~ welcome to communicate ~!

John Smith and his friend bill jones had an accident in the Pacific Ocean, and the boat finally drifted to an uninhabited island. They have enough fish and fruit, but no reading materials, only a joke book. Every joke is countless. At first, John and Bill amused themselves by reading joke books in turn and told each other this joke. A year later, they knew all about these jokes and even remembered the joke numbers.

When John tells this joke, Bill will be laughed at.

When Bill answers this question, John will also think of this joke and laugh.

When they spent many, many years on this desert island, one day, another man was shipwrecked and drifted to this desert island.

He asked them both, "How do you usually live?" Bill said, "We tell jokes to each other" and took out a joke book at the same time.

John said, "Tell us a joke, just read the joke number."

The man replied "Yes". He leafed through the joke book and saw a joke that he thought was very interesting. This is the 83rd joke.

He said, "I found one. Are you ready? "

John and Bill answered "Yes".

The man said, "This is the 83rd joke."

John and Bill stared at the man. They were expressionless and silent. The man asked, "Why don't you laugh?" Bill said, "Because what you said is not funny at all." .
