Events in a Mental Asylum

John and David were both patients in a mental hospital. One day, John suddenly dived into the deep end of the swimming pool. David jumped in and saved him and the medical director came to know of his heroic act.

Doctor: We have good news and bad news for you, David: The good news is we are going to discharge you because you have regained your senses, since you are able to jump in and save another patient. The bad news is, the patient whom you had saved hung himself in the toilet.

David: He didn't hang himself. I hung him there to dry.
