Stuart and Walt were both patients in a mental hospital. One day while they were walking past the hospital swimming pool, Walt suddenly dove into the deep end.

He sank to the bottom and stayed there. Stuart promptly jumped in to save him. He swam to the bottom of the pool and pulled Walt out. The medical director came to know of Stuart's heroic act... He immediately ordered that Stuart be discharged from the Mental hospital, as he considered him to be okay.

The Director said, "We have good news and bad news for you, Stuart! 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. Walt, hung himself in the bathroom, and died."

Stuart replied, "Doctor, he didn't hang himself, I hung him there to dry".
