Entering their epic senior year at Greendale Community College, these people aren't just a study group, they're family! They'll have to be, if they hope to survive a comedy-crammed year with everything from an alienating sci-fi convention, a German re-invasion and a Thanksgiving dinner from hell, to a hostage taking Christmas, a life-changing father/son reunion and even an epic transformation into puppets! In its wildly inventive fourth season, this phenomenal comedy hits an incredibly hilarious, new level! Prepare to "Pop! Pop!" with laughter.
