Name of video: Diagnosis Wenckebach

Performers: University of Alberta 2010 med school class

Why it's worth watching: Our favorite of several medical school videos set to Justin Timberlake's "SexyBack." Not only is it a pretty professional job for a bunch of 20-somethings, with nice video editing, the "Timberlake" guy is a charmer. (Doctors, do they have their medicine right here?)
