A man comes running to the doctor shouting & screaming in pain.
Man: "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 and shouting: "Which one?"
Man innocently: "How am I to know? All bees look the same to me."
