Bill and Mary were patients in a mental hospital. Both were considered dangerous to themselves as well as to others. However over their years of confinement the two of them developed a deep friendship for one another that some even thought was romantic in nature.

One day while they were out walking past the hospital swimming pool, Bill suddenly jumped into the deep end and sank to the bottom of the pool where he stayed.

Mary seeing the situation promptly jumped in to save him. She swam to the bottom and pulled Sean out. Once out of the water she helped him with his breathing. 

When the Medical staff became aware of Mary's heroic act they convened a special meeting and decided she could now be discharged from the mental hospital, as they now considered her to be mentally stable.

When the Administrator went to Mary's room to tell her the news she said, 'Mary, I have good news and bad news for you.

The good news is we are going to discharge you from the hospital today. Since you were able to rationally respond to a crisis by jumping in and saving the life of the person you love ... the staff has concluded that your act displayed you have a sound mind.

The bad news Mary is your friend Billl hung himself last night in his bathroom with his bathrobe belt after you saved him. We are all so sorry for your loss as we all knew how much he meant to you.'

Mary replied, 'Bill didn't hang himself, I put him there to dry.

Now how soon before I can go home?'
