What inexplicable laughs have you ever shared?

I heard a little joke like this before. It was so interesting that if I didn’t laugh it off, I would laugh for no reason.

There was a man who failed to catch the bus after get off work in the evening. In order to get on the bus, he rode a bicycle to chase the bus. As a result, he did not catch the bus until he got home.

He returned home out of breath and said happily to his wife: "Today, I chased the bus and saved another two yuan."

His wife glanced at him Bai, smiled and said: "You chase, you also chase the taxi, at least you can earn a starting price."

He touched his head and nodded hurriedly.

Once, I was alone in a daze. I thought about this and laughed. People around me looked at me strangely. I woke up and was so embarrassed.
