Fred and Becky were both patients in a mental hospital. One day as they both walked beside the swimming pool, Becky jumped into the deep end and sank to the bottom. Without a thought for his own safety, Fred jumped in after her, brought her to the surface, hauled her out, gave her the kiss of life and saved her.
The next day happened to be Fred's annual review. He was brought before the hospital board, where the director told him, "Fred, I have some good news and some bad news: the good news is that in light of your heroic act yesterday, we consider that you are sane and can be released from this home and back into society. The bad news is, I'm afraid, that Becky, the patient you saved, shortly afterwards hung herself in the bathroom with the belt from her bathrobe. I'm sorry, but she's dead."
Looking puzzled, Fred replied, "She didn't hang herself, I put her there to dry."
