I am O negative. I got into an argument with the doctor when he said that. I said: "Can't be, I am always, alwáys positive." He said: "Well, your test came back negative, so that's a positive." I replied: "Oh, you are just trying to get me to see this negative as positive. I don't buy it mister white coat wisenose." He got angry and yelled at me: "O NEGATIVE!!!" Then he pushed his buzzer and screamed: "NEXT!!"
