An American tourist
An American tourist was driving in County Kerry, when his motor stopped. He got out to see if he could locate the trouble. A voice behind him said, "The trouble is the carburetor." He turned around and only saw an old horse. The horse said again, "It's the carburetor that's not working." The American nearly died with fright, and dashed into the nearest pub, had a large whiskey, and told Murphy the bartender what the horse had said to him.

Murphy said, "Well, don't pay any attention to him, he knows nothing about cars anyway."

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.�
