Can you tell jokes?

Once there was an air crash, all the passengers survived, and no boxes were found, except a pet monkey brought by the pilot. Investigators had to try to communicate with monkeys.

Investigator: "Monkey, monkey, what are you doing on the plane?"

The monkey made a gesture of eating.

The investigator was overjoyed and further persuaded: "What is that stewardess doing?"

The monkey made a move.

The investigator was happier: "What is the pilot doing?"

The monkey made a swinging motion on the steering wheel with his hand.

The investigator gave the monkey a banana and then asked, "What was the stewardess doing before the accident?" ? "

The monkey made a gesture of unbuttoning.

The investigator was surprised: "So what is the pilot doing?"

The monkey kept hugging and kissing.

The investigator was furious, but he didn't forget to ask, "Then what are you doing?"

The monkey waved the steering wheel again.
