A man comes running to the doctor shouting and screaming in pain.
"Please doctor, you've got to help me. I've been stung by a bee."
DOCTOR: "Don't worry; I'll put some cream on it."
MAN: "You will never find that bee. It must be miles away by now."
DOCTOR: "No, you don't understand! I'll put some cream on the place
you were stung."
MAN: "Oh! It happened in the garden where I was sitting under a tree."'
DOCTOR (in anger): "No, no, you IDIOT! I mean on which part of your
body did that bee sting."
MAN (still screaming in pain): "On my finger! The bee stung me on my
finger and it really hurts."
DOCTOR : "Ok.Which one?"
MAN (innocently): "How would I know? All bees look the same to me."
