I read some articles about old dumb laws in NY that few people know about. Apparently, these are violations that no one would be fined for in practice because they are so archaic that not even law-enforcers are aware of them. However, I was unable to find any primary source that confirms that any of those laws are actually in place.

• A fine of $25 can be levied for flirting.
• A license must be purchased before hanging clothes on a clothesline.
• Carmel: A man can't go outside while wearing a jacket and pants that do not match.
• Citizens may not greet each other by "putting one's thumb to the nose and wiggling the fingers".
• Donkeys are not allowed to sleep in bathtubs in Brooklyn, N.Y.
• During a concert, it is illegal to eat peanuts and walk backwards on the sidewalks.
• In New York, you can teach your pet parrot to speak, but not to squawk.
• In New York City it's illegal to shake a dust mop out a window.
• It is against the law to throw a ball at someone's head for fun.
• Jaywalking is legal, as long as it's not diagonal. That is, you can cross the street out of the crosswalk, but you can't cross a street diagonally.
• Slippers are not to be worn after 10:00 P.M.
• Staten Island: You may only water your lawn if the hose is held in your hand.
• While riding in an elevator, one must talk to no one, and fold his hands while looking toward the door.

Can anyone confirm if any of these are real laws in NY?
