Can anyone send me a humorous joke?

A group of people were waiting for urine tests in the hospital corridor, each holding their own urine sample in their hands. The nurse called a patient named Wang Shangju and shouted: Wang Shangju! All patients then raised their urine samples a little higher. The nurse shouted again: Wang Shangju! .....Then the patients raised the urine sample a little higher...and the nurse shouted: Wang Shangju! ! ! Then all the patients raised their urine samples high. At this time, Wang Shangju realized that the nurse was calling him, so he answered loudly: "Here!" Then all the patients peed on their heads.
