The Curious Incident of Dr More in the Night.

Dr: "Hello there, what's your problem?"
Woman: "I'm pregnant."
Dr: "O dear, I'm not sure how we treat that, I fell asleep for the bit in medical school where they talked about tropical diseases."
Woman: "No, I'm pregnant."
Dr: "O, let me see. I'll get my stethoscope. Big breh."
Woman: "What?"
Dr: "Big breh."
Woman: "What did you say? Are you slagging me melons?"
Dr: "What?"
Woman: "O, whatever."
Dr: "I just checked your urine sample and...well, it appears you actually have prostate cancer."
Woman: "But that's impossible, I don't have a prostate!"
Dr: "O really? I'm sorry, I must have switched off for that part of anatomy and physiology. Do you have a mickey then?"
Woman: "Are you taking the piss?"
Dr: "Well, I just did a moment ago, but I can get Susan to look at it if you'd prefer a woman doctor to do it. Or that Masterson woman, she's pretty good at sorting out mickeys."
Woman: "Doctor, I don't know what's wrong with you, but you're just freaking me out."
Dr: "O. It seems that was actually the urine sample of a 74 year-old male patient of mine. That explains why it didn't show you up as being pregnant. I play the organ you know."
Woman: "You what?"
Dr: "Eh, never mind. Big breh."
