I haven’t experienced this with people in my department (history) but based on my experiences so far, this is a very common first conversation with other Harvard graduate students (especially law school students):

A: What is your name?
B: Konrad
A: Where did you go to undergrad?
B: Western Washington University
A: Oh

Besides the fact that my undergraduate institution, which I’m very fond of, is not an elite ivy league school, it also fits into the ridiculed category of what my recent PhD graduate friend calls, “East Jesus Tech” or any schools where are “directional colleges”, religious/denominational, or technical colleges.
