As a goofy internal medicine resident, Y would definitely get along with JD from Scrubs. You'll hear over and over again that Scrubs is the most realistic medical show out there, and judging by the people i've met in Y's program -- and the stories he tells me -- that is most definitely the case.
Thank goodness, because I don't think he could handle someone getting in a life threatening accident every week. (I'm looking at you, Grey's Anatomy.)
