hmmm... 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."
