John and David were both patients in a mental hospital. One day while they were walking past the hospital swimming
pool, John suddenly dove into the deep end. He sunk to the bottom and stayed there. David promptly jumped in,
swam to the bottom of the pool and pulled John out.
The medical director became aware of David's heroic act. He immediately ordered that David be discharged from the
Mental Hospital, as he considered him to be OK.
The Doctor said, "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 sanity. 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 hung himself in the bathroom, and died."
David replied, "Doctor, he didn't hang himself.....I hung him there to dry."
