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 sunk 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 Mary the news he said, "Mary, I have good news and 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, Jim, the patient you saved, hung himself with his bathrobe belt in the bathroom. I am so sorry, but he's dead."

Mary replied "He didn't hang himself, I put him there to dry!"
