that he was doing, he put a pen cap into his mouth. A few minutes
late, he was terrified to find that he had swallowed it! The teacher
was shocking when the boy stood up and said, "I've just swallowed
a pen cap." He was quickly sent the nearest hospital. There a doctor
examined him and said the best treatment was to take some medicines
so that the pen cap could pass natural. Three hours later the boy
