Two doctors were in a hospital hallway one day complaining about Nurse Jenny.

"She's incredibly dumb. She does everything absolutely backwards," said one doctor.

"Just last week, I told her to give a patient 2 milligrams of percocet every 10 hours. She gave him 10 milligrams every 2 hours. He nearly died on us!"

The second doctor said, "That's nothing. Earlier this week, I told her to give a patient an enema every 24 hours. She tried to give him 24 enemas in one hour! The guy nearly exploded!"

Suddenly, they hear this blood-curdling scream from down the hall.

"Oh my God!" said the first doctor, "I just realized I told Nurse Jenny to prick Mr. Smith's boil!"
