Nurses' professional jokes

There is a long line in the urology clinic, and everyone is waiting for a urine test with his own urine cup in his hand. One of them is Wang Shangju, who is in his fifties and has a hard ear. When the nurse called him: Wang Shangju (lifted it), both of them lifted the urine cup, and the nurse was bored. Well, why did they all raise their urine cups? Call again: Wang Shangju (lift it), everyone is bored, how can this nurse tell us to lift the urine cup? Give up when you scream. Everybody up. The nurse is in a hurry. Shout loudly: Wang Shangju (lift it up). Just then, Wang Shangju heard the nurse calling him, and he shouted: Go (down)! Everyone fell down when they heard it. Wow, one after another, one after another, all fell on the nurse ...?
