I shouldn't have asked

Every morning I ask the residents I work with to read a chest x-ray.  We go over how to properly diagnose all the problems that are seen.  In order to do this we do it systematically so that nothing is missed.  As a joke one morning I used my own chest x-ray.

The first diagnosis, "a large amount of subcutaneous tissue".  Loosely translated this means REALLY fat.  

I guess the joke was on me.
