Mine:
Little annoying-- "Your blood pressure is a little high. Sit for a minute and calm down and we'll redo it. If it doesn't come down, we'll talk about what's next." (What?! Like I can voluntarily control that!)
Little shocking-- hearing that I have "one BIG baby in there" and that he'd bet the baby's "pushing 9lbs" as I was like 10 min away from delivery. (Great timing AND word choice there, Doc.)
Little funny-- my (female) OB commenting on my french manicured nails as I was holding my legs back, pushing! (Just funny...it made me laugh and lightened the mood for a moment, actually.)
