What do you do when it's your last first day of school ever? Why, go to your happy place to keep from panicking, of course! Abed's happy place is Greendale Community College as a live sitcom, with Fred Willard as Pierce. At school, the whole gang is excited about senior year - they're determined to make it count. When they round the corner to their History of Ice Cream classroom, they see that it's been overbooked, but Jeff, who got there uncharacteristically early, saved them all seats.
