A woman goes to the doctor, beaten black and blue.The Doctor asks: "What happened?"The woman says: "Doctor, I don't know what to do. Every time my husband comes home drunk he beats me to a pulp."The Doctor says: "I have a real good cure 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.The woman says: "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! How does the tea do that?"The Doctor says: "The tea does bugger all, it's keeping your mouth shut that does the trick"
