Who will play a joke or riddle "One ear goes in and the other ear goes out"?

On a certain day of a certain year, a person felt uncomfortable and painful in his ears, so he went to the hospital to see a doctor. The doctor said, "Your ears are really beautiful." The man said, "I heard someone cut my ear for the first time." The doctor said, "You can see the right ear directly from the left ear. It's a veritable left ear goes in and the right ear goes out! "
