Your old disease has come back

What a smart doctor! I wouldn't go to them.

一个年轻的医生给病人检查完了身体，不能确定到底是什么病。就问病人﹕“你以前得过这种病吗﹖”病人回答﹕“是啊。”医生高兴地说﹕“那就对了，你原来的病又复发了。”

A young doctor finished examining a patient's body, but couldn't confirm what type of disease it was. So he asked, "Have you caught this disease before?" the patient replied, "Yup." the doctor said enthusiastically, "That's right, your old disease has come up again."
