From the History Channel's website:

"1919: Prohibition takes effect

The 18th Amendment to the U.S. Constitution, prohibiting the manufacture, sale, or transportation of intoxicating liquors for beverage purposes," achieves the necessary two-thirds majority of state ratification, and thus becomes the law of the land."

Now, THAT's something that's REALLY nothing! And I certainly wouldn't celebrate it, 'cause it sent my grandfather to jail. (Fortunately, we have his still still.)
