Catbert walks on the wall of Wally's cubicle. He thinks, "The evil director of human resources spots his prey." Catbert stands on top of Wally's computer and says, "Wally, you haven't filled out a vacation request form yet." Catbert continues, "If we don't get it by tomorrow, you lose your vacation." Wally asks, "Where do I get a form?" Catbert replies, "We're all out." Wally is furious and screams, "Did they ever exist?" Catbert says, "Wally, does anything really exist, or is it all just shadows on a cubicle wall?" Catbert stands and says, "I leave you with that thought." Catbert continues walking on the wall of the cubicle as Wally bangs his head on his desk. Catbert thinks, "Who says philosophy is useless?"
