A man was hit by a cab in the street. He was brought to the hospital. His wife who was standing up by his bed, said to the doctor: "I think that he is very ill."
"I am afraid that he is dead." said the doctor,
Hearing this, the man moved his head and said: " I'm not dead. I'm still alive."
"Be quiet, " said the wife. "The doctor knows better than you!"
