Considering the lack of crossover between people who worked on Buffy the Vampire Slayer and people who worked on Community (just a handful of undistinctive guest stars – most notably, the old lady from “Doublemeat Palace” voices Pierce’s mom; some stunt people, and a few miscellaneous crew), this Easter egg is even more awesome. Though as much as Troy and Abed love Firefly, it’s likely they’ve checked out other Joss Whedon-related stuff.
Now we know what happened to all of the old textbooks from UC Sunnydale. : buffy.
Hah, wow, neat. Now I am wondering if perhaps the name “Greendale” is paying homage to “Sunnydale.”
