Laughing for the same joke

I was out at a restaurant today that had hung up a short story on the wall. It was about a man who got on stage and told the audience a joke. The audience laughed loudly.

He then repeated the joke.

A few people laughed this time.

He repeated the same joke for the third time.

No one laughed.

To this, he said – “You can’t laugh at the same joke over and over again. Why do you then keep crying and complaining about the same problems?”

Why indeed?
