Stuck Lettuce

"Doctor, doctor! You've gotta help me!" cried the scared woman. "I have a piece of lettuce stuck in my ear!"

"That looks nasty." commented the nurse.

"Nasty?!?" replied the doctor. "You haven't seen anything yet."

"What do you mean?" asked the nurse and alarmed patient, in unison.

"This is just the tip of the iceberg!" replied the doctor.
