Here are some more from my other home state:
- Children over the age of eight can't wet the bed
- Cats that meow in the dark get their tails cut off (what the f**k is THAT about?!?!)
- It's illegal to crash into obstacles while skiing in Vail (now I know that when I take up skiing, I shouldn't start there)
- Car dealers can't show cars on Sundays
- Liquor stores can't sell food, and grocery stores can't sell alcohol, except beer with less than 3.2% alcohol (that one's true)
- You can't have upholstered furniture outdoors in Boulder
- Throwing missiles at cars is illegal in Alamosa
- Abusing rats is illegal in Denver (yet cats get their tails cut off if they meow in the dark?)
- Insulting a cop is legal in Boulder, but only until he/she asks you to stop (Ozzy, I think I found your place! You can insult those vegan cops until they say to stop!)
- In Sterling, cats that run loose need to have tail lights (but what if the cat was caught meowing in the dark?)
- Tags can be cut off of pillows and mattresses (dang it, how do I know what's in those things around here?!

)
- It's illegal to let a dandelion grow within Pueblo city limits (I guess you can always put coins in wishing wells)
- Dog catchers in Denver have to notify the dogs they plan to catch for three consecutive days by putting flyers on a tree in the city park and along a road that goes through the park (because dogs can read flyers and will know to either brace themselves or get the heck out

)
- Cross-dressing is illegal in Durango (good thing Mrs Doubtfire wasn't filmed there

)
- Driving black cars on Sunday is illegal in Denver (my mother actually broke that law once, and I think I saw a bunch of other people in black cars that day, so I guess that one's not really enforced)
- In Colorado Springs (where I live right now), it's legal to wear a holstered six-shooter, but not on Sundays, election days or national holidays (so I guess I shouldn't get people to vote or wish them a merry Christmas by wearing a revolver on my belt)
- It's illegal to mutilate a rock in a Colorado state park (I guess Cera better keep her horns to herself

)
- It's also illegal to move a rock on city property in Boulder (I think Cera ought to just play it safe and keep away from Boulder and Colorado state parks

)
- Riding a horse while drunk is illegal (I wonder if the same goes if you're stoned; it is Colorado, after all)
- Until 2008, selling alcohol on Sundays or election days was illegal
- In Cripple Creek, you can't bring a horse or mule above the first floor of any building (I better get all my horses over there out of the attic!!)
- In Denver, you can't loan a vacuum cleaner to your next-door neighbor
- Snowball fights are illegal in Aspen (yet it's NOT illegal to throw a missile at someone's car like it is in Alamosa?!)
- In Westminster, it's illegal to get lost between 9PM and 4AM, or to get lost while someone else is driving your car (I guess it's important to get good directions there!)
- In Fountain, it's illegal to have a broken-down car on private property or any public right-of-way (good thing Subarus are so popular)
- Men aren't allowed to kiss women in their sleep in Logan County
