How about a riddle.
A woman brings her husband to the doctor.
The woman explains, "My husband has not spoken for 5 years. For the first 22 years I knew him he never had an issue like this and then suddenly, one day, he could not speak. It's not that he doesn't want to speak, it's that he can't speak. He can't speak to his friends, his children or anyone else. I've tried everything but nothing will make him speak."
The doctor asks the man if what his wife says is true. The man nods sadly. The doctor examines the man and finds nothing abnormal. The doctor asks the couple if anything traumatic happened around the time he stopped speaking. His wife says no and the husband shakes his head no. "Absolutely nothing happened that we can think of that could have caused this," the wife says.
The doctor thinks for a minute, leaves the room and returns with a hammer. "I want you to put your hand on the desk," the doctor says. The man puts his hand on the desk. The doctor grabs his wrist, making sure the man can't move his hand. "If you don't tell me 'NO' on the count of three I am going to smash your hand with this hammer." The man begins to tremble. "ONE!" The man is turning read and trying to get the word out of his mouth. "TWO!" The man is sweating, shaking and trying everything he can to speak."THREE!" The doctor slams the hammer down on the desk about six inches to the right of the mans hand. He lets go of the mans wrist. The man exhales and collapses into a chair. The man was not able to speak.
The doctor is perplexed. "Well, I don't have an explanation. I don't believe you're faking it, the hammer test proved that. I've never seen anything like this." The man is dejected. His wife comforts him and thanks the doctor for his time. They turn to leave the office and the doctor stops them. "Wait a second," the doctor asks. He runs to his desk and writes something on a piece of paper. He picks the paper up and excitedly hands it to the man who reads it. His eyes get big. He looks at the doctor and sound begins to emerge from his throat. The man's vocal chords awaken, "uhhhhhooooohhhh my goodness! I can speak! Honey, I can speak!" His wife, now in tears, embraces him. She hugs and thanks the doctor as does her husband. "I'll never be able to thank you enough, doctor." The happy couple leave the office and live happily ever after.
