Plus isn't this the second time we see Greendale "doubles" for the study group? Back in season 1 Troy and Abed have a very brief scene with a pair of security guards who were look-a-likes and now we have had Britta and Annie with not only their look-a-like doubles but at least with Britta pretty much the same personality. I wonder if they'll go the
How I Met Your Mother route and show everyone's double.
