When my daughter was about five, she uttered a bad word: "Sh*t." Trying to head this language off, I told her not to say that when she was mad but to say, "Shoot a monkey." That afternoon she heard her dad say, "Damn." So she marched up to him, with her hands on her hips, and totally bewildered him by saying, "Don't say 'damn' -- say 'monkey sh*t'!"
