OP: "Professor, I don't know what to do my dissertation for my degree in Stuff Apple Makes. Can you offer any ideas?"
Professor: "Well you could try doing it on those things that Apple uses in their packaging. You know the plastic sleeve things that go on cables and stuff. You should be able to get a hundred pages on that. Oh and try to find out what they're called."
OP: "That's a great idea! By the way, MacRumors.com is considered a valid research source by the university, right?"
