One day a doctor of the madman was experimenting to see the improvement of the three mad ones. If you can pass the examination, release will be restricted for two more years if not done. The doctor asked the three to go in front of a water swimming pool and jump to jump. The first crazy jumping along with the legs broke the legs. The second madman also jumped as the doctor said and broke his hand. But the third madman did not agree to jump. The doctor screamed with joy and said, 'Hey, you are perfectly healthy. I will release you today. Tell me why you did not jump? In response, he said, 'I do not know swimming'.
