A short joke with the same sound but different words? urgent

There are many homophones in Chinese, which are sometimes difficult to understand.

It is said that Secretary Jiao worked hard day and night and was admitted to the hospital from overwork. After a period of treatment, his condition has greatly improved. Before leaving the hospital, the attending doctor told him: Secretary Jiao, don't rush to work after you go back, rest for a few days, and don't share a room for a month.

Doctor, you don't know, Secretary Jiao said. My family only lives in one room. How can I live in different rooms?

When the doctor knew that Secretary Jiao had misunderstood, he said, I mean, you can't share the same bed.

Secretary Jiao said with a smile: My family has a big kang, and there are many children. Where do you sleep in separate beds?

When the doctor saw that Secretary Jiao didn't understand, he said directly: I mean, you can't have sex!

Now Secretary Jiao is unhappy: I have been surnamed Jiao since my ancestors, and the dolls at home are also surnamed Jiao. You can't tell my last name is Jiao, so I'm not Jiao? !
