Dilbert and Dogbert stand in the hallway of a couple's house. The man says, "We're so glad you guys could stop by." Dilbert replies, "Thanks for inviting us." Dogbert thinks, "We hardly know them." The woman says, "I'd offer you some coffee, but that would be a bother." Dilbert says, "Uh . . . None for me. Thanks." The woman says, "I noticed you didn't bring any food as a courtesy to your hosts. I guess we'll eat when you leave." The man says, "We usually watch television now, but I'll try not to appear bitter about your visit." The man and woman sit in chairs while Dilbert and Dogbert sit on the floor. The man asks, "Why haven't we done this sooner?" Dogbert replies, "We thought you were scum."
