A man entered a hospital seeking a medical examination. When he entered the examination room, the doctor noticed he was quite dirty and said:
– Please go over there and clean yourself up before I examine you.
The man replied, “Yes,” and stepped outside. Half an hour later, he returned:
– Doctor, I’m done!
The doctor looked up, frowning:
– What happened? You look even dirtier than before!
– Well, it’s because… the hospital restroom was so dirty that I had to use all my strength to scrub it clean.
