Orthopaedics vs Anaesthetics
Someone at work pointed me at this. I've watched it about five times in the last couple of days, while showing it to other people, and it still cracks me up every time. You don't have to know anything about orthopaedic sugeons or anaesthetists to get the joke, although it is slightly enhanced by knowing that a patient presenting with asystole would colloquially be said to be 'flatlining'.
