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!”
