Stephanie: Sheldon, what are you doing here?
Sheldon: Hang on. 130 over 80. A little high. We can attribute that to the stress of sneaking past the security desk.
Stephanie: Where did you get the stethoscope and the blood pressure cuff?
Sheldon: My aunt Marion gave them to me for my 12th birthday. She thought if I failed at theoretical physics that I should have a trade to fall back on. And by the way, the blood pressure cuff is called a sphygmomanometer.
Stephanie: Thank you.
Sheldon: Didn't they teach you that in medical school?
