Remember that time my doctor called me a cow?

So at my doctor's appointment last week I had an interesting experience. I was up on the table, big white belly exposed and Doctor listening to the heartbeat with his doppler whatever thingy. Nurse has me by the right hand and is trying (in vain apparently) to squeeze drops of blood out of a pin hole in my finger. She is squeezing and squeezing with all of her might, and Doctor says "it's just like milking a cow."

And Kate says, "things not to say to your patient."
