Two doctors are in the hallway complaining about nurse Nancy. ''She's out of control!'' the first doctor says. ''She does everything backwards. Just last week I told her to give a man two milligrams of morphine every ten hours, she gave him 10 milligrams every two hours, he alomost died!'' ''That's nothing,'' said the second doctor, "earlier this week I told her to give a man an enema every 24 hours, she tried to give him 24 enemas in one hour!'' All of a sudden they heard a blood curldling scream from down the hallway. ''OH MY GOD! I just realized that I told nurse Nancy to prick Mr. Smiths boil!'''
