Mrs. Nutmeg goes to the doctor and says "Doc: My husband is loosing his temper and it's getting worse every day. What can I do?"
Doc: When you see it starting to happen, take a full glass of water, put some in your mouth, and swish it around - just keep swishing and swishing until he calms down.
Two weeks later she returns and says "Doc, that was great. How does that work?"
Doc: Actually it has nothing to do with the water and everything to do with keeping your mouth shut!
