Strange federal crimes

18 U.S.C. §1657: It's illegal to consult with a known pirate.

21 USC §333 & 21 CFR §102.39: It's a crime to sell onion rings resembling normal onion rings but made from diced onion, without saying so.

27 USC §§205, 207 & 27 CFR §4.64(a)(8): It's a federal crime to advertise wine in a manner that suggests it has intoxicating qualities.(That's right - it's illegal NOT to false advertise)

15 U.S.C. §§330a & 330d: Attempting to change the weather without telling the Secretary of Commerce is illegal.

18 U.S.C. §1857: It's a crime to knowingly let your pig enter a fenced-in area on public land where it might destroy the grass.(May have been important a couple centuries ago.)

All of this just goes to show how obsolete some laws have become as the world has developed. What lawmakers from the early stages of the US found important and relevant to society are not necessarily useful, sometimes even detrimental, to what is important today.
