John & David were both patients in a mental hospital.
One day they were walking past the hospital swimming
pool and John suddenly dove into the deep end. He
sunk to the bottom and stayed there.
David jumped in to save him. He swam to the bottom
of the pool and pulled John out.
The medical director came to know of David's heroic
act. He immediately ordered that David be discharged
from the mental hospital as he considered him to be okay.
The doctor says, "We have good news and bad news for you, David!
The good news is that we are going to discharge you
because you have regained your senses. Since you were
able to jump in and save another patient, you must be
mentally stable. The bad news is that the patient whom
you saved, Mr. John, hung himself in the bathroom and died."
David replied, "Doctor he didn't hang himself. I hung him there to dry."
