45. West Virginia: Whistling Underwater
Some historical laws are physically impossible to break, making their continued existence completely baffling to modern legal scholars. A heavily documented state law dictates that it is completely illegal to whistle while underwater. The precise origins of this specific phrasing remain a complete mystery. It is highly likely the law was originally meant to ban a specific type of disruptive aquatic signaling device or a dangerous, breath-holding swimming game. However, the resulting legal text was drafted so poorly that it ended up strictly forbidding a biological action that human lungs cannot actually physically perform while submerged.
