A Sardar 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."
sardar : "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."
sardar : "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."
sardar (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?"
sardar (innocently): "How am I to know? All bees look the same to me."
