It's Earl and Fran's 20th wedding anniversary - the Grapdelite anniversary. Earl purchases a pair of Grapdelites, which are described sweet-tasting, adorable little mammals. Earl's friends comment about the increasing scarcity of the Grapdelites, and one jokes that Earl might have the last pair on Earth. Earl gives the pair to Robbie to hide until the anniversary. The Grapdelites befriend Robbie and confirm that they are the last of their species. Robbie becomes concerned for their fate and, after discovering that the pair consists of one male and one female, suggests that they have children.
