A woman goes to the doctor. She says to him “Every time my husband comes home, he ends up attacking me, and it’s giving me bruises everywhere and I just want it to stop.”
The doctor replies “I have just the trick. What you need to do is get a jawbreaker, and whenever your husband comes home, just put it in your mouth and suck on it. No matter what, just keep sucking on it. Your problems will go away in no time.”
The woman seems surprised by this trick, but she agrees to try it.
One month later, the woman returns to the doctor. With excitement, she tells him that the jawbreaker trick has worked, and that her husband no longer hurts her. The doctor responds “Good, now you know the value of keeping your mouth shut.”
