When it comes to laws, every state has its fair share of strange and outdated regulations. But in Wisconsin, there are a few laws that stand out as particularly odd. Here’s a look at one of the most unusual laws on the books in the Badger State.

In Wisconsin, it is illegal to serve apple pie in public restaurants without a slice of cheese on top. Yes, you read that right: cheese is required on top of any apple pie that is served in a public restaurant in Wisconsin.

While the origin of this law is unclear, it is thought to be a nod to Wisconsin’s status as a major cheese producer. And while many Wisconsinites take this law as a point of pride, others view it as a quirky relic of a bygone era.

Of course, the law is rarely enforced, and most restaurants in Wisconsin happily serve apple pie with or without cheese. But for those who take their pie and cheese seriously, the law is a reminder of the state’s unique culture and traditions.
