"Remedial Chaos Theory" is the fourth episode of the third season of the American television series Community. The episode was written by Chris McKenna and directed by Jeff Melman. It originally aired on October 13, 2011 on NBC. It follows a community college study group at a housewarming party for members Troy (Donald Glover) and Abed (Danny Pudi). When Jeff (Joel McHale) throws a die to determine who will go to collect the pizza delivery from downstairs, seven different timelines unfold, showing each member of the group leaving to collect it depending on the outcome of the die—including the canonical timeline, in which Abed catches it before it lands. The episode was intended to be the third episode of the season, but was delayed by a week due to filming, editing and visual effects overr
