Joke translation

One afternoon, I went to school by bus. There were not many people on the bus, and a woman got up from her seat to buy a ticket. At this time, there was a young man sitting in the empty seat next to her who wanted to get off. The woman who bought the ticket found that the seat had been occupied, and said with a happy face, "It won't lay eggs, but it will be occupied in the pavilion!" " Hearing this, the young man gave up his seat and said to her, "I'm sorry for keeping you from laying eggs."
