From quirky to downright strange, New York City is host to a slew of laws that might make you scratch your head. These laws, some dating back to the 19th century, provide an interesting insight into the city's past and present. Here are seven bizarre laws that are still surprisingly on the books in NYC.

1. The Ice Cream Sunday Law

In the late 19th century, it was illegal to sell ice cream on Sundays in NYC. The law was intended to enforce observance of the Sabbath. Today, we thankfully don't have to worry about our ice cream cravings on Sundays.

2. No Puppet Shows in Windows

Under NYC Administrative Code 10-114, it's illegal to host puppet shows in your window. This was intended to prevent crowds gathering and blocking the streets.

3. No Wearing Slippers After 10 PM

Believe it or not, it's illegal to wear slippers after 10 PM in New York. The origin and intent of this law are still up for debate, but it's a fun piece of NYC legal trivia nonetheless.

4. No Jumping Off Buildings

Under NYC law, jumping off a building is not only dangerous but also illegal and punishable by death. While it's a grim law, it underscores the seriousness of safety concerns.

5. No Spitting

The practice of spitting on public sidewalks was banned in the early 19th century to combat the spread of tuberculosis. The law is still in effect today, promoting public cleanliness.

6. Adultery is a Crime

Adultery, believe it or not, is still technically a crime in New York State. Conviction could lead to a fine or even jail time, although prosecutions are exceedingly rare.

7. No Using Clotheslines in Certain Areas

According to the New York City Administrative Code, using clotheslines is prohibited in certain districts. This law is aimed at maintaining the aesthetic appearance of these areas.

While most of these laws are not actively enforced today, they remain part of NYC's legal fabric, adding to the city's unique character and charm. They serve as reminders of the city's dynamic history, social norms, and continually evolving cultural landscape. Who knows? You might even find yourself partaking in a whimsical debate over the validity of slipper wearing after 10 PM!
