Two doctors were talking about one of the nurses at their hospital... "She seems very confused sometimes, and she always gets things mixed up! Last week I asked her to give Mrs. Frederikson two pills every twelve hours, and she gave her twelve pills every two hours!" "I know, I Know" replies the second doctor "I observed something similar: I told her to feed one spoon of cough-syrup to the kid in room 15 every five hours, and she gave him five spoons every single hour!" Just at that moment, a terrible cry of pain and agony was heard in every hallway of the hospital. "Oh shit!!" Exclaims the first doctor "I just told her to prick Mr. Johnsons boil!!"
