Bill was 60 years old and he was ill. He was always tired and his face was always very red. He did not like doctors. But last month his wife said to him:"Bill,go and see Doctor Brown." Bill said,"No." But last week he was worse,and he had to go to the doctor's. Doctor Brown said to him:"You drink too much. Stop drinking beer and drink milk." Bill liked beer but he didn't like milk. "I'm not a baby." He always said to his wife. Now,he looked at Doctor Brown and said:"But drinking milk is dangerous. Doctor." The doctor laughed and said:"Dangerous. How can drinking milk be dangerous?" "Well,doctor," Bill said,"It killed one of my best friends last year." The doctor laughed again and said:"How did it do that?" "The cow fell on him."Bill said.
