A man comes running to the doctor shouting & 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 (banging his fist, abusing and shouting): "Which one?"
MAN (innocently): "How am I to know? All bees look the same to me."
