Judges

The book of Judges is a record of pre-monarchical Israelite history and how, because of the loose tribal rule, it all just went to total shit over there. It is book-ended by the recurrent phrase, "'In those days there was no king in Israel; all the people did what was right in their own eyes.'"which most scholars agree is God's way of saying, "I got nothing to do with this."

Contents and interpretation
Holy shit, they just cut her up. They cut her right the fuck up.

Canonical status
The book of Judges has long been preserved through the nightmares of children whose parents scarred them by encouraging them read it in lieu of some violent comic book or something. It was admitted to the canon when scholars unanimously agreed it was too fucked up to ignore.
