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 almost 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 curdling scream from down the hallway.

''OH MY GOD! I just realized that I told nurse Nancy to prick Mr. Smiths boil!'''
