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, abusing and shouting): Which one?

MAN (innocently): How am I to know?! All bees look the same to me!!!
