Strange Laws You Didn’t Know Were Illegal in Your State

Most Americans assume they have a pretty good understanding of what’s legal and what isn’t—but some laws on the books are far stranger than you’d expect. Across the country, outdated, unusual, and downright bizarre rules still exist, and many people have no idea they could technically be breaking them.

From odd restrictions on everyday behavior to laws that seem frozen in time, each state has its own collection of legal quirks. While many of these rules are rarely enforced, they’re still officially on the books—and they can be surprisingly specific.

At 24/7 Tempo, we dug into state laws and historical records to uncover some of the strangest things that are technically illegal across the United States. The results highlight just how unusual—and often overlooked—American law can be.

In Alabama, it’s illegal to wear a fake mustache in church that's funny enough to cause people to laugh. The law is intended to preserve the sanctity of religious services. Though rarely enforced, it’s still on the books.

Alaska prohibits hunting moose out of airplanes, and even spotting them from aircraft can raise legal questions. This law aims to prevent hunters from using planes unfairly, showing off Alaska’s strict game and hunting protections.

It’s illegal in Arizona to let a donkey sleep in a bathtub. This stems from a 1920s incident where a flood washed away a bathtub with a donkey inside of it. Though oddly specific, the statute is a reminder of how quirky history influences modern rules, as those who rescued the donkey demanded that this action be illegal in the future.

In Little Rock, Arkansas, specifically, it’s illegal to honk your horn outside a sandwich shop after 9 PM. While rarely enforced, it shows how city ordinances can be hyper-local. Businesses and residents alike pushed for quiet evenings, and so the law was born.

In Berkeley, California, you can’t whistle for your lost canary before 7 AM. This strange local ordinance is a noise control measure, likely stemming from neighborhood complaints in dense housing areas. It’s one of many peculiar California municipal codes aimed at minimizing disruption.

Some Colorado towns have ordinances requiring homeowners to remove dandelions promptly. This is considered a public nuisance and can result in fines. This law is more about HOA-style aesthetics than environmental concerns.

According to an old Connecticut law that turned out to be a myth, a pickle must bounce to be legally sold. The statute was created to prevent fraudulent or spoiled food sales and created a group of true pickle connoisseurs. Officials once tested pickles by dropping them a foot off the ground. If they didn’t bounce, they weren’t fit for consumption under the law, no exceptions.

It is technically illegal in Delaware to whisper in church. This law is about preserving order during religious services, and even whispering during a sermon can violate this rule. While rarely enforced, it could be something the average person gets in trouble for without realizing.

Florida once had a law against singing while wearing a swimsuit in public. The rule targeted beach behavior and ‘lewd conduct’; though not regularly enforced, it’s still occasionally cited in weird law roundups and public decency records.

In Gainesville, Georgia, it’s illegal to eat fried chicken with utensils. This law is largely ceremonial, but was originally passed to honor Southern traditions. A tourist was once ‘arrested’ as part of a publicity stunt for breaking it; they were, of course, later released.

It’s against the law in Hawaii to put coins in your ears, apparently. The rule stems from public safety concerns and past injury cases. Though rarely prosecuted, it is technically part of Hawaii's state health code.

An old Idaho law forbids gifting someone a box of candy weighing over 50 pounds. The law was meant to discourage excessive or coercive gift-giving, and remains one of Idaho’s quirkiest legal relics.

In some parts of Illinois, it’s illegal to fall asleep in a cheese shop. The law is rarely enforced, and its origins are unclear; it may have emerged from health or sanitation regulations. Regardless, it still exists in the state’s municipal code in some counties.

In Indiana, noodling, which is a colloquial phrase meaning to catch fish with your bare hands, is illegal. The law is designed to protect fish populations and prevent injury. Despite its popularity in other Southern states, Indiana banned the practice. Violators could face fines or even jail time for this hands-on fishing method.

It’s against the law in Iowa for a man with a mustache to kiss a woman in public. This outdated statute reflects turn-of-the-century social decorum; mustaches are in a surprising number of old U.S. laws. Though never enforced today, it remains in the state’s law books.

In Kansas, it’s technically illegal to serve ice cream on cherry pie on Sundays. This law dates back to a time of strict Sunday observance and isn't enforced today. However, the rule remains on the books and is largely viewed as humorous.

In Kentucky, you can reuse your own milk cartons, but you can’t reuse a milk carton that belongs to someone else. The law was intended to prevent contamination and brand misuse, and modern violators could technically face fines or minor penalties.

In Louisiana, it’s actually illegal to send someone a pizza delivery they didn’t order. This law was passed to prevent prank orders and protect businesses, and repeat offenders may even face jail time. It treats pizza fraud as a form of harassment and theft of services, despite it seeming like a well-intentioned idea.

Maine has a statewide law requiring Christmas decorations to be taken down by January 14th. Violators may be fined under local ordinances. The rule is about maintaining neighborhood aesthetics, and it’s one of the few places where festive procrastination can cost you big time.

Maryland has strict laws about oyster handling, including penalties for abusing them. Even improper storage or rough treatment can count as abuse, so be sure to brush up on how to properly harvest and collect oysters should you ever plan on doing this in Maryland.

In Massachusetts, singing 'The Star-Spangled Banner' incorrectly or as part of a medley is illegal. Performers may face fines or write-ups if they alter the lyrics or tempo. It’s one of the few laws governing musical expression in the U.S., but thankfully it only applies to the National Anthem.

In Michigan, it’s technically illegal to serenade your lover at night. This statute dates back to anti-noise ordinances in residential areas and is, for the most part, outdated. However, it’s still technically valid in some counties.

Minnesota reportedly bans crossing state lines with a duck on your head. The origins of this law are unclear, but it is likely rooted in folklore, treated as something more amusing than serious. No known arrests have occurred under this law, but you never know!

In Mississippi, public profanity is still outlawed in many counties. The law is enforced sporadically, often brought up during public disturbances. Plus, swearing in front of minors can carry heavier penalties, so it's best to watch your mouth in this state!

In Missouri, it’s illegal to drive with an uncaged bear in your vehicle, and was likely passed after incidents involving circus or roadside attraction animals. Missouri takes unexpected road hazards very seriously, so be sure to keep your pet bear properly caged when traveling.

Montana law prohibits leading sheep onto train tracks in an effort to prevent rail delays and animal casualties. It’s one of many livestock-related laws still active in the state, and ranchers must follow specific transport rules to avoid fines.

In some areas of Nebraska, burping during church service can be considered a misdemeanor. The law is rarely enforced, but still exists in local codes. It's just another example of laws surrounding how the U.S. chooses to respectfully worship.

Certain Nevada cities have laws against sitting or lying down on sidewalks, though they're typically enforced against unhoused individuals. These rules were passed as anti-loitering measures, and violators may be ticketed or fined. Civil liberties advocates frequently challenge these ordinances in court, but it's a stubborn rule that remains.

At one point in time, New Hampshire prohibited patrons from tapping their feet in bars or taverns. The law was meant to prevent unlicensed dancing, but it is obviously no longer enforced. However, the rule technically made it illegal to enjoy music too enthusiastically.

New Jersey has distracted driving laws that include drinking coffee. Though not explicitly banned, drivers have been ticketed for sipping behind the wheel. Critics say the rule is too broad and inconsistently enforced, but state officials urge drivers to avoid all food and beverage distractions while driving.

In New Mexico, using the state anthem for commercial or disrespectful purposes is against the law. Violations could potentially result in fines, much like other states that require residents to respect the National Anthem.

A bizarre New York law bans wearing slippers after 10 PM in public. This rule was reportedly based on health concerns tied to foot odor and hygiene. Though not enforced, it’s still technically valid and on the books.

In North Carolina, it’s illegal to sing off-key in public. This rarely-enforced law is tied to old anti-noise ordinances and was intended to discourage disruptive behavior during public events. Still, no pitch tests are required...yet.

Some North Dakota towns prohibit sleeping with your shoes on inside buildings. Much like the slippers law, this law was designed to maintain cleanliness in public and boarding houses. Today, it's mostly regarded as an odd relic, but one worth mentioning.

In Ohio, it’s illegal to get a fish drunk. This unusual animal protection law prohibits alcohol exposure to aquatic life, likely based on older anti-cruelty statutes or events. Even if rarely enforced, it’s still technically binding.

Oklahoma law actually forbids making ugly faces at dogs. The rule is about preventing animal provocation or cruelty. Though the law seems humorous, it's rooted in animal welfare. Fines can apply if a dog owner reports harassment, so make sure to only look at Oklahoma dogs with love and respect.

In Oregon, using canned corn to fish for trout is illegal. It's designed to protect fish from harmful or artificial bait, but it's also a lesser-known regulation among outdoor enthusiasts. Violators could face fines from Oregon's fish and wildlife officers.

In Pennsylvania, it’s illegal to use goldfish as prizes at carnivals or games, and it is part of broader protections for animals in entertainment. Carnivals can face penalties for noncompliance, which is why many in this state and others have phased out this once-common practice.

Rhode Island still has a law criminalizing 'biting off a limb'. Though obviously illegal as assault, the wording reflects outdated language that has been cited in humorous legal rundowns. No one’s trying to test this one, thankfully, but it's only a matter of time...

Like Arizona and their donkey law, South Carolina bans keeping horses in bathtubs. The law originated from an incident where a horse was tragically swept away during a flood. While it's an event that rarely happens, the image alone is unforgettable.

Like Illinois, South Dakota has a law against falling asleep or falling down in a cheese factory. This regulation was created to avoid workplace injuries, but it's thankfully rarely necessary to enforce it.

A recent law in Tennessee states it’s illegal to share your streaming service passwords. The law was passed to combat piracy and unauthorized access, and violators could face misdemeanor or felony charges, depending on the case. It applies to services like Netflix, Hulu, and Disney+.

Texas prohibits the sale of human organs, including eyes. While part of broader regulations on organ trafficking, the notion is odd on its own. Even attempting to sell body parts could lead to prison time, so don't try this one at home.

In Utah, milk is the official state beverage, and some counties require it to be served with school meals. While not illegal, refusing milk in certain programs has sparked controversy. Students often challenge the rule on dietary or religious grounds, pointing out the ludicrousness of such a law.

Vermont’s Constitution once disqualified atheists from public office. Though now unenforceable due to federal protections, the clause remains written in official documents. It’s just a historic artifact of an earlier era now, as modern courts will strike it down if invoked.

In Virginia, it is illegal to use profane language on the telephone. This law is part of the state’s broader rules about public decency and telecommunications, as violators can technically be fined for swearing during a call, even today.

Skamania County, Washington, passed a law making it illegal to harass or kill Bigfoot. Originally enacted in 1969, it classifies Bigfoot as an endangered species. While largely symbolic, the law reflects the state's cultural fascination with the creature, and violating this law could result in a misdemeanor or fine.

In West Virginia, there is an old local ordinance that reportedly bans whistling underwater. While likely intended as a joke or novelty, the law has appeared in legal trivia. Its absurdity makes it memorable, even if completely unenforceable.

In some parts of Wisconsin, it's considered improper, and reportedly illegal, to serve apple pie without cheese. The law isn’t actively enforced, but it reflects the state’s dairy pride and the fact that this was once a Midwestern staple endorsed by local lawmakers.

Wyoming law requires that if you open a gate on someone’s property, you must close it afterward. This rule is essential for protecting livestock and maintaining ranch operations, and it's honestly just common courtesy. Violating it can lead to fines and civil liability if you're caught, so always be sure to leave a gate in Wyoming exactly as you found it (though preferably closed).
