OB at the end of a 2 minute exam: ” Any questions?”
Mother: “Yes, could you tell me my blood type?”
OB, glancing at chart:  ”Your blood type is O-, which is a problem.”
Mother: “Why is that a problem?”
OB, backing out of exam room:  ”It means your blood could kill your baby, but we’ll worry about that later. See you next month.”
