Strong Medicine for the Nun

Pat is not feeling very well and he decides to go to a doctor. While he is waiting in the doctor's reception room, a nun comes out of the doctor's office. She looks very ashen, drawn and haggard. Pat goes into the doctor's office and says to the doctor: "I just saw a nun leaving who looked absolutely terrible. I have never seen a woman look worse." The doctor says: "I just told her that she is pregnant." Pat exclaims: "Oh my, is she?" The doctor responds: "No, but it sure cured her hiccups."
