In Pennsylvania, it is illegal to sleep on a refrigerator, but only outside.

You might not realize it, but there are actually quite a few laws determining how and when you can sleep. In fact, in Pennsylvania it is completely illegal to sleep on your refrigerator outside. 

If you are inside, however, it is okay to sleep on top of your refrigerator. Despite the discomfort of sleeping on said refrigerator, it is apparently done enough to warrant the writing of a law. In addition to determining where you can sleep, governments across the United States are determining how you’re allowed to sleep and what you can do to other people who are asleep. 

Here are some other strange laws about sleeping: 

• In Oklahoma, it is illegal to wear boots to bed. They must be removed before falling asleep. On the flipside, wearing shoes is perfectly okay. 
• In Washington State, you must ask permission before sleeping in someone else’s outhouse. That would be a cramped, smelly place to sleep! 
• Not all laws apply only to humans sleeping. Horses also have laws to follow too. It is illegal to let a horse sleep in a bakery in Santa Ana, California.
