Chickens May Not Cross the Road and Other Crazy (but True) Laws by Kathi Linz, illustrated by Tony Griego

From chapters.ca:
It is against the law in Brooklyn, New York, for donkeys to sleep in bathtubs. In Idaho you are not allowed to fish while sitting on a giraffe. In California you must not keep slugs as pets. Yes, it's the law - says so right on the state or city books. Some of the most ludicrous laws in the history of America come to light in this funny and fascinating book for children who have a special appreciation for the tyranny of silly rules.
