The Messy Nurse

The nurse was walking down the hospital corridor when her supervisor spotted her. The supervisor couldn't believe it:

The nurses hair was unkempt, her dress wrinkled, and to top off her overall dishevelment, one of her breasts was hanging out of the open front of her uniform!

"MISS JENNINGS! How can you account for parading around the hospital not only looking like a derelict, but with your breast exposed!"

"Oh," said the nurse, as she stuffed her breast into her uniform, "It's those darn interns! They NEVER put anything back when they're through using it!"
