Here are some of my favorites:
In Chicago, IL it is forbidden to fish while sitting on a girraffe's neck.
In Galesburg, IL there is a $1000 fine for beating rats with baseball bats.
In Horner, IL it is against the law to use a slingshot unless you are a law enforcement officer. (I wonder if that is their new sidearm.)
In California, no vehicle without a driver may exceed 60 mph. (I think this is for the new self-driving cars, but it's still scary.)
In California, it is illegal to shoot any kind of game from a moving vehicle, unless the target is a whale. (I hope they're assuming that your vehicle is a boat for shooting whales, otherwise Shamu's in danger.)
In Chico, CA detonating a nuclear device within the city limits is a $500 fine.
In Fresno, CA no one may annoy a lizard in a city park.
In Los Angeles County, CA you may only throw a frisbee at the beach with the lifeguard's permission.
In Fresno, CA permenant markers can't be sold in the city limits. (Never live in a city that doesn't trust it's citizens with Sharpies.)
In Hollywood, CA it is illegal to drive more than two thousand sheep down Hollywood Blvd at one time.
In Los Angeles and Los Angeles County:
You can't hunt moths under a street light.
It's illegal to cry on the witness stand.
Toads may not be licked.
It's illegal for a man to beat his wife with a strap wider than 2 inches without her consent.
You can't bathe two babies in the same tub at the same time.
It is illegal to skateboard and rollerskate through the courthouse and library.
In Norco, CA if you want a rhinocerous as a pet it will cost you $100 for the liscense.
In Ontario, CA roosters may not crow within the city limits. (Go ahead and give the bird the fine.)
In Palm Springs, CA it is illegal to walk a camel down Palm Canyon Drive (Main street) during rush hour (4-6 p.m.).
In Portola, CA it is illegal to fish from an overpass in the city. (Having trouble catching that bus?)
In Redlands, CA Motor vehicles may not drive on city streets unless a man with a lantern is walking ahead of it. (Ever heard of headlights?)
In San Diego, CA it is illegal to shoot jack rabbits from the back of a streetcar.
In San Diego, CA the owners of houses with Christmas lights on them past February Second may be fined up to $250. ("Officer, those are Hanakkah lights. We don't celebrate Christmas.")
San Francisco has some of the funniest ones:
Persons classified as "ugly" may not walk down any street. (I've been there. Half the city should be in jail for this.)
It is illegal to pile horse manure more than 6 feet high on a street corner. (5 foot 11 inch high manure on every street corner is legal? That town must stink.)
The law prohibits elephants from strolling down market street unless they are on a leash. (Like a leash is going to hold back an elephant.)
It is illegal to wipe one's car with used underwear.
In Santa Monica, playing percussion instruments on the beach is illegal.
In Thousand Oaks, CA one must obtain a special permit from the city manager before having a "going out of business" sale. (You can actually be too broke to go broke?)
In Walnut, CA kites may not be flown higher than 10 feet above the ground. (If you see me there, I'll be the one selling kids helium balloons with long strings.)
In Kendall, NY it is against town ordanances to camp on your own land for more than 72 hours a month. If you want to camp out for two weeks you need a permit, which you can only get once a year. (So much for property rights.)
New Yorkers can't dissolve a marriage for irreconcilable differences, unless they both agree to it. (If you can't agree to disagree, you're stuck disagreeing for life.)
In Arizona, it's illegal to manufacture imitation cocaine. (They don't want the criminals cheating them with the fake illegal narcotics.)
I once saw a sign in Arizona saying there was a $50 fine for parking on the railroad tracks. (That's cheaper than some parking structures.)
At a local hiking trail, Iron Mountain near Poway, CA, they "improved" the trailhead by putting in a well lit parking lot and added a sign saying that the hours for hiking were between sunrise and sunset. Further, the trail wasn't city property but went through private property given away for hikers so the city of Poway had no jurisdiction to even tell people they couldn't hike at night. When I confronted the guy who had the sign put up, he said hikers would not be ticketed at night because the parking lot would be used as a park and ride, but hiking at night would be (with emphasis) at your own risk.
In Mira Mesa, CA there is a sign that says "No Bike Riding Rollerblading Skateboarding Dogs". Shame on them for denying talented pets from having fun.
