Two hearts beating

　　Nurse: How do you feel after your operation?

　　Patient: Quite alright, only I can feel two hearts beating inside me.

　　Nurse: No wonder the doctor who operated on you was looking for his watch everywhere just now.

　　护士：手术后你感觉怎样?

　　病人：十分好，只是我能感觉到我体内有两颗心脏在跳动。

　　护士：怪不得给你做手术的`大夫刚才在到处寻找他的手表。
