A man went to an insurance office to have his life insured. The manager of the office ask him how old his parents were when they were died. “Mother had a bad heart and passed away at age of 30. Father died of tuberculosis (肺结核) when he was 35.” “I’ m very sorry,” said the manager, “We can’ t insure our life as your parents were not health” Disappointing, the man left the office. He met a clerk who had listened their talk. “You mustn’t be so frank and tell the truth.” said the clerk. “Not office will insure you if you speak like that. Use your imagination a little.” The man went to other office and was shown into the manager’ s room. “Well, young man, how old were your parents when they died?” “Mother was 93, and died while she was play football.”
