These are supposedly actual signs that have appeared at various locations.

Outside a country shop: "We buy junk and sell antiques."

In the window of an Oregon store: "Why go elsewhere and be cheated when you can come here?"

In a Maine restaurant: "Open 7 days a week and weekends."

In the vestry of a New England church: "Will the last person to leave please see that the perpetual light is extinguished."

In a Pennsylvania cemetery: "Persons are prohibited from picking flowers from any but their own graves."

On a roller coaster: "Watch your head."

On the grounds of a public school: "No trespassing without permission."

On a Tennessee highway: "When this sign is under water, this road is impassable."

In front of a New Hampshire car wash: "If you can't read this, it's time to wash your car."

In a Maine restaurant: "Open 7 days a week and weekends."

Some people will still ask if they're open on Saturday or Sunday, trust me, people are that stupid.

On my way to school everyday I used to walk past a sign that read "Main Street Mental Health, Entrance In rear".
I regret never taking a picture of it, the place is now a chinese buffet
