An example:
New York
A fine of $25 can be levied for flirting. This old law specifically prohibits men from turning around on any city street and looking "at a woman in that way." A second conviction for a crime of this magnitude calls for the violating male to be forced to wear a "pair of horse-blinders" wherever and whenever he goes outside for a stroll.
It is against the law to throw a ball at someone's head for fun.
A license must be purchased before hanging clothes on a clothesline.
The penalty for jumping off a building is death.
We think the last one is most sensible
