Mr. Wilson invites a doctor to his home to see his wife. After
letting the doctor into her room he waits outside.
Soon the doctor pops his head out and asks: "Mr. Wilson,
do you have a can opener?"
Mr. Wilson gives him a can opener
. After a while the doctor asks for pliers. Later he asks for
a
hammer.
Finally Mr. Wilson asks nervously: "Doctor, what's wrong
with my wife?
The doctor answers: "I don't know. I haven't been able to
open my medical case!"
