These are supposedly actual signs that have appeared at various locations...
On a door: "Push. If that doesn't work, pull. If that doesn't work, we must be closed."
Message on a leaflet: "If you cannot read, this leaflet will tell you how to get lessons."
Outside a photographer's studio: "Out to lunch: if not back by five, out for dinner also."
In a store: "Prices subject to change according to customer's attitude."
Next to a swimming pool: "Welcome to our ool. Notice there's no 'p' in it. Let's keep it that way."
A man worked for a road crew. One day he woke up ill with a touch of laryngitis, but being a dedicated employee, he went to work. The boss felt rather sorry for the worker and didn't want him to do any physical labor, as they were repairing a part of the freeway.
He says, "Why don't you go down the road and tell people to slow down going through the construction?"
The worker is glad for the easy day. He stops the first vehicle. "Sir," he whispers, his throat feeling worse, "please slow down, there's a road crew up ahead."
"Okay," the driver whispers back, "I'll try not to wake them."
A woman went into a hardware store to purchase a bale of peat moss. She gave a personal check in payment and said to the clerk, "I suppose you will want some identification."
He replied, without hesitation, "No ma'am, that won't be necessary."
"How come?" asked the woman.
"Crooks don't usually buy peat moss," answered the clerk.
Two factory workers are talking. The woman says, "I can make the boss give me the day off."
The man replies, "And how would you do that?"
The woman says, "Just wait and see." She then hangs upside down from the ceiling.
The boss comes in and says, "What are you doing?"
The woman replies, "I'm a light bulb."
The boss then says, "You've been working so much that you've gone crazy. I think you need to take the day off."
The man starts to follow her and the boss says, "Where are you going?"
The man says, "I'm going home, too. I can't work in the dark."
