Actual Answer from a Medical Student
While making his rounds, a doctor points out an x-ray to a group of medical students.

�As you can see,� he says, �the patient limps because his left fibula and tibia are radically arched.�

The doctor turns to one of the students and asks, �What would you do in a case like this?�

�Well,� ponders the student, �I suppose I�d limp, too.�
