Jim and Mary were both patients in a Mental Hospital. One day while they were walking past the hospital swimming pool, Jim suddenly jumped into the deep end. He sank to the bottom and stayed there. Mary promptly jumped in to save him. She swam to the bottom and pulled Jim out.
The medical director learned of Mary's heroic act. He immediately wrote orders for her discharge from the hospital. He considered her mentally stable. When he went to tell Mary the news. He said, "Mary, I have good
news and bad news. The good news is you're going to be discharged. You jumped into the pool and saved the life of another patient. I believe you've regained your full mental capacity and you are able to function normally in society. Here are your discharge papers.
The bad news is, Jim, the patient you saved,hung himself in the bathroom with the belt to his bathrobe. I am so sorry, but he's dead."
Mary replied "He didn't hang himself. I put him there to dry."
