Strange legal practices can often be found in various countries, where laws may seem unusual or outdated. For example, in Switzerland, it is illegal to own just one guinea pig because they are social animals and need companionship. This law reflects the country's commitment to animal welfare. Another peculiar practice is the ancient law in England that allows a person to claim a piece of land if they can successfully "squat" on it for a certain period. This law, known as "adverse possession," can lead to surprising outcomes, as individuals may gain ownership of property simply by occupying it without permission.
