The United States Constitution
The United States Constitution is considered to be the smallest and most stable Constitution in the world.
Americans are so respect their Constitution that does not even bring in the main text of the amendment - they publish a separate application at the end of the main text. By the way, the First Amendment to the US Constitution states that "Congress shall make no law abridging the freedom of speech and the press." Almost every state has some interesting ban: Wisconsin forbidden to drink beer and sell after 9 pm, and in Michigan this prohibition is valid for all Sundays. The state of Utah is illegal to swear in the presence of the deceased, a resident of Kentucky, at least once a year is required by law to take a bath. In Alabama it is prohibited by law to use for plowing cotton fields of elephants and in Arizona is forbidden to hunt camels - hardly anyone suffers from this law, because the camels are not found.
