The Herdmans are absolutely the worst kids in the history of the world. They lie and steal and smoke cigars (even the girls). They talk dirty, hit little kids, cuss their teachers, set fire to Fred Shoemaker's old broken-down toolhouse, and take the name of the Lord in vain. Still, no one is prepared when the Herdmans invade church one Sunday - and decide to take over the annual Christmas pageant.
