Greendale Community College sure knew how to get into the Halloween spirit, and here are all of the Community Halloween episodes ranked. The study group in focus always took an opportunity to attend a campus party, and thankfully for them, their classmates took the spooky holiday seriously. When not attending class, the study group — Jeff, Annie, Shirley, Pierce, Troy, Abed, and Britta — always found something to do on campus, and of the six seasons, all but two of them featured a pop-culture-referencing and very meta Halloween-themed episode.
