It was half pass three. The doctor just lay down to have a nap when he heard a loud knock on the door. He got up and asked the man at the door: "What is it?"

"I've been bitten by a dog," said the man painfully.

"Well, don't you know that my hours of consultation are between twelve and three?" said the doctor unpleasantly.

"I know," groaned the man, "but that confounded（困惑的） dog didn't know, It bit me at twenty past three."

下午三点半钟时，医生刚刚躺下想小睡一会儿，就听到有人大声敲门。他起身问门口的人：“什么事呀？”

门口那个人痛苦地说：“我被狗咬了。”

医生很不高兴地说：“哦，你不知道我诊病的时间是12点到3点吗？”

那个人呻吟着说：“我知道，可是那只该死的狗不知道。它在3点20分咬了我。”
