The First Amendment

When you're senile, rich or animated, you can get away with saying just about anything you want.  The rest of us have to use hushed tones when telling ethnic jokes and think of creative ways to swear, like telling the cab driver to go to h-e-double hockey sticks or calling your mother-in-law a see you in Tahiti.

While the first amendment protects heretics and traitors, nothing can protect you from the personal shame of an ill-received racial slur or poo joke.
