For anyone wondering: the two body problem is a phenomenon that happens when two academics marry. They both want an academic job together, at the same institution preferably, but there's usually only enough room for 1. What many couples do to solve this is accept postdocs at different universities (because there's a two body problem for post docs too, so you can't usually find 2 postdoc positions at the same institution), and then wait around until they can find two assistant professorship openings at the same institution. Sometimes if the candidate is really good, one department will ask another to make room for another faculty there. But that can be a political nightmare. Or if both researchers are in the same field e.g. CS, then the department might have to hire both even if they really only would take the one. It's quite a problem for hiring.
