The guys learn that a professor has died at the university, meaning that a position on the tenure track has opened up. Sheldon, Leonard, Koothrappali, and Kripke are all viable candidates for the position, so they get into a bit of a competition. They learn that Ms. Davies in HR is on the tenure committee, so they all try to impress her to gain an advantage, but they wind up offending and irritating her. Finally, the whole group goes to a mixer, where they argue with one another over who deserves tenure the most. In the end, Ms. Davies recommends all three of them, despite their quirks, because they are all very accomplished in their fields.
