If you're in pain and a sound comes out of your mouth.

There is a joke: "A Korean guy, whose last name is Lee, marries a Persian girl. Her name is Mina, and she goes to medical school. At her graduation, everyone is called to get their diplomas, and the girl goes up and her name is called: 'Dr. Mina Lee'!" [which basically means Dr. Painful-Groan]
