Beware of your words and thoughts if you are in Massachusetts, it is a crime to be an atheist:
Whoever wilfully blasphemes the holy name of God by denying, cursing or contumeliously reproaching God, his creation, government or final judging of the world, or by cursing or contumeliously reproaching Jesus Christ or the Holy Ghost, or by cursing or contumeliously reproaching or exposing to contempt and ridicule, the holy word of God contained in the holy scriptures shall be punished by imprisonment in jail for not more than one year or by a fine of not more than three hundred dollars, and may also be bound to good behavior.

I wonder what it means to be 'bound to good behavior'?
