One thing that parents learn quickly is that kids often seem to imitate their behavior at the worst possible times.
Sure, sometimes they'll say something nice in the exact way mommy or daddy said it, but they're just as likely to start giving the finger like it's going out of style after the one time they saw their parent do it during rush hour.
And as one Florida woman learned, this "monkey see, monkey do" behavior isn't just limited to humans. Or monkeys, for that matter.
