The old joke

In ancient times, there was a bald man who hated being called bald. One morning I went out to empty the urinal, and the urine came out of the spout, making a "chug chug" sound. The bald man was very unhappy. He said, you also laugh at my baldness. I don't want you. Say that finish, conveniently threw the urinal into the water field. As soon as the urinal fell into the deep water, the spout was filled with water as soon as it was lifted, making a sound of "bang (not bald) bang (not bald)". Hearing this, the bald man smiled and said, you said you were bald, and I'll pay you back if you know you're sorry.
