Are those laws actually on the books? Searching the laws of New York, I've been unable to actually find any of these supposed laws, and nearly everytime this comes up, the only citation for these laws still existing is other lists of crazy/insane/weird laws, with no one actually giving a specific reference to the law.

Edit: Actually, I did find a reference for one of the saner "weird laws": PEN § 240.35 paragraph 4 does define "Being masked or in any manner disguised by unusual or unnatural attire or facial alteration, loiters, remains or congregates in a public place with other persons so masked or disguised, or knowingly permits or aids persons so masked or disguised to congregate in a public place;  except that such conduct is not unlawful when it occurs in connection with a masquerade party or like entertainment if, when such entertainment is held in a city which has promulgated regulations in connection with such affairs, permission is first obtained from the police or other appropriate authorities" as loitering.
