Who knows this joke.

It is said that there was an old man who came to the city for the first time. He remembered his daughter telling him that people in the city called "public toilets" instead of "thatched rooms". He wanted to use the toilet but couldn't find it, so I went to ask passers-by, but I forgot how to say it. I just remembered that it was called a public place. I didn’t want the passers-by to hear it confused. What is a public place? The man pointed at a movie theater. The movie theater should be a public place. . The old man walked to the door of the cinema and was about to enter. He was stopped by the cinema ticket inspector: "Your ticket?"

"Do you still need a ticket to enter here?"

"Of course, please go there. Buy a ticket.”

The old man thought, it’s different in this city, you have to buy a ticket to use the restroom. So I bought a ticket and went in. But he had never seen such a toilet before. After looking around, the waiter found his seat for him according to his ticket. The old man thought, after all, the city is a city, and you have to take your seat when going to the toilet. But he found that there were many people in the cinema, including men and women, and there were lights. He was puzzled and asked the people around him: "Are all men and women here together?"

The man watched She looked at him and said, "Yes."

He didn’t dare to ask more questions, thinking that since this was the rule, let’s not break it, “But why are you still keeping the lights on?”.

"Turn off the lights when it starts."

"When will it start?"

"It will start after the bell rings."

The old man finally understood. This time it was an eye-opener. In this city, everyone has to go to the toilet together and have their own place. But why men and women are together and they have to turn off the lights before starting, he still doesn't understand. But the delay in ringing made him very anxious.

Finally the bell rang, the lights went dark, and what the old man had been holding back for a long time finally happened...

At this time, someone from behind patted the old man on the shoulder, but the old man ignored him. After a while, the person from behind He patted the old man again. The old man was a little unhappy and replied in a bad voice: "Mind your own business. What's the matter with you?"

The enthusiastic voice of the young man from behind: "Uncle!! Your baked sweet potato fell on my foot!" !
