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 like a stone to the bottom And stayed there. Mary promptly jumped in to save him. She swam to the bottom and pulled Jim out.
When the medical director became aware of Mary's heroic act, he immediately ordered her to be discharged from the hospital, as he now considered her to be mentally stable.
When he went to tell her the news, he said, "Mary, I have good news & bad news. The good news is you're being discharged because since you were able to jump in and save the life of another patient, I think you've regained your senses". "The bad news is that Jim, the patient you saved, hung himself >in the bathroom with the belt of his robe. I am so sorry, but he's dead."
Mary replied, "He didn't hang himself, I put him there to dry." Mary is back in her old room.
