Both Wikipedia and The Big Bang Theory Wiki say that Sheldon Cooper of the Big Bang Theory has a Master of Arts degree. They both cite "The Love Car Displacement" episode as the source for that. But I can't find any mention of that in the episode's script.
Does Sheldon really have a Master of Arts degree? That seems very strange for someone who has devoted his entire life to science, and who has such a strong disdain for anything non-science related (and even certain sciences like geology). If he does have a M.A., what field is it in?
