What are some funny messages businesses put on changeable letter signs?

Some funny messages businesses put on changeable letter signs include "Slow down. The cop hides behind this sign" and "Drop your pants here and you will receive prompt attention," posted by a local cleaner. Businesses use wit and creativity to come up with funny messages for signs.

Many businesses create witty messages that are relevant to their market. For example, a car repair center sign states "We are the best place in town to take a leak," a bar sign displays "No free Wi-Fi. Talk to each other and get drunk" and even a Burger King restaurant located beside a torn down McDonald's can't help but put up a sign that reads "RIP McDonald's."
