Doctor: "What happened?"
Woman: "Doctor, I don't know what to do. Every time my husband comes home drunk he beats me to a pulp."
Doctor: "I have a real good medicine for that. When your husband comes home drunk, just take a glass of sweet tea and start swishing it in your mouth. Just swish and swish but don't swallow until he goes to bed and is asleep."
Two weeks later the woman comes back to the doctor looking fresh and reborn.
Woman: "Doctor, that was a brilliant idea! Every time my husband came home drunk, I swished with sweet tea. I swished and swished, and he didn't touch me!"
Doctor: "You see how much keeping your mouth shut helps?"
