An 82-year-old man yawned so much one day that his chin's joint fell out of place.

As a result, he cannot fully close his mouth or speak clearly in the past weeks. He dribbled until he was taken to the hospital in Shijiazhuang, Hebei province, for treatment. A doctor returned his chin to the right place.

The doctor also told him that he shouldn't open his mouth too wide when he yawns in order to avoid ripping his ligaments.
