Maybe this is only funny when you've been in graduate school and hung out with PostDocs, but I laughed so hard, I had to pause the TiVo.
I don't expect them to hit on that same note over and over. Well, Sheldon does, but that's Sheldon.
I only leave in the last quoted paragraph, because I think with the joke, you're seeing everything as a nail. (Mixed metaphor?)
I see that as simply a "I'm more educated than you" joke, not some deep graduate school joke. Even if that one was done by the department chair, Sheldon repeatedly makes the "I'm smarter/more educated than you" joke (which is why I left in the quoted part).
I don't see it as being any different, just given by a different person.
