A blind man walks into a restaurant and sits down. The waiter, who is also the owner, walks up to the blind man and hands him a menu. “I’m sorry, sir, but I am blind and I can’t read the menu. Just bring me a dirty fork from a previous customer and I’ll order from that.” A little confused, the owner walks over to the dirty dish pile and picks up a greasy fork. He returns to the blind man’s table and hands it to him. The blind man puts the fork to his nose and takes a deep breath.
“Ah, yes, that’s what I’ll have, meat loaf and mashed potatoes.” Unbelievable, the owner says to himself as he walks towards the kitchen. Mary the cook happens to be the owner’s wife and he tells her what just happened. The blind man eats his meal and leaves. The owner thinks the blind man is screwing around with him. He tells his wife that the next time the blind man comes in he’s going to test him. He returns the following week, but this time the owner sees him coming and runs into the kitchen. He tells his wife, “Mary, rub this fork on your panties before I take it to the blind man.” Mary complies and hands her husband the fork back. As the blind man walks in and sits down, the owner is ready and waiting. “Good afternoon, sir. This time I remembered you and I already have the fork ready for you.” The blind man puts the fork to his nose, takes a deep whiff and says, “I didn’t know Mary worked here.”
