A friend of mine had a 3 year old that cussed like a sailor. He tried everything under the sun to break him of it. At his wits end he made up a story that he told to his son about an old mean man that kidnaps little kids with potty mouths and treats them real bad until they learn to talk nice. The three year old's response?
"WELL, THAT SON OF A B*TCH"
