Summary: Sassy and Waldo have continued to wear a trench coat and attend school because they love being near their boy, Stewart, and because they particularly love lunch when they get to eat meat instead of kibble; now that Stewart has (reluctantly) joined the Junior Office Supply Enthusiasts club they get to stay later--but because of the lack of snacks the two dogs start exploring the empty cafeteria and end up starting a sandwich club.
