A woman goes to the doctor, beaten black and Blue. 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 a sleep."  
 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 keeping your mouth shut helps?"
