One day a dentist was starting his morning work. Suddenly a man ran in. His face was red and he could only say “Quick! Quick!” The dentist thought he must be very ill. His assistant helped to make the poor man sit in a chair. The dentist gave the man some medicine to make him sleep. Then, he looked into the man’s mouth and pulled out all the bad teeth. As soon as the man woke up, he said in a low voice, “Quick, doctor, quick.”
