One doctor says to another doctor; I think that I will have to fire nurse Smith.
So the other doctor ask him how come?
"Because she keeps getting things backwards. The other day I told her to give Mr. Jones in room 301 one pill every four hours. She ended up giving him 4 pills every hour. I then told her to change the bandage on his head. She ended up making his bed."
All of a sudden they heard this horrible scream coming from Mr. Jones's room.
So the doctor says, "Oh No" I will definitely have to fire nurse Smith now; I told her to go in and prick Mr. Jones boil."
