One day, a man goes into a chemist's shop(药店) and says, "Do you have anything to cure(治疗) a headache?"
The chemist(药剂师) takes a bottle from a shelf, holds it under the man's nose and takes out the cork (软木塞). The bottle gives out a special smell. The smell is very strong. Tears come into the man's eyes and run down his face. "What do you do that for?" he says angrily when he can get back his breath (呼吸).
"The medicine can cure your headache," says the chemist.
"Don't be silly!"" says the man, "My son has a headache, not me!"
