Well I don't see a link for DC although I'm sure there's some dumb laws still on the books. Of note is a law requiring all bicycles operated in the city to be registered. This law is only enforced if a cyclist is causing some other trouble like participating in a protest that blocks traffic.
Since there was no link for DC, I checked out some for the state where I gew up, Tennessee.
Here's some for Memphis.
Memphis
- Illegal for a woman to drive a car unless there is a man either running or walking in front of it waving a red flag to warn approaching motorists and pedestrians.
- It's illegal for frogs to croak after 11 PM.
- Panhandlers must first obtain a $10 permit before begging on the streets of downtown Memphis.
- It is illegal to give any pie to fellow diners. It is also illegal to take unfinished pie home. All pie must be eaten on the premises
Here's one for Fayette County, where I actually lived about an hour east of Memphis, that isn't totally dumb.
Fayette County
- You may not have more than five inoperable vehicles on a piece of property.
I'm not sure how much this law is enforced, but some people would actually let broken down cars collect on their property in the front yard no less till their property looked like a junk yard, which might be ok if they were actually a junk yard, but if its in front of a residence, it starts to look tacky. This law doesn't seem any dumber than laws requiring people to keep their grass cut and to shovel snow from the sidewalk. Maybe its highlighting the dumbness of people who required such a law to be written.
