Noriko, holding a 'Do Not Disturb' sign, says to Dilbert, "This sign is my passport to cubicle tranquillity." Putting up the sign on the outside of her cubicle, Noriko says to Dilbert, "I wonder why no one ever thought of it before." Noriko, sitting at her computer, frowns angrily as Wally says, "Nice sign. Does it keep away the undesirables?"
Dilbert is talking on the telephone and says, "Is this Skeptics Association? I need your help to prove my rat isn't psychic." Dilbert holds the phone and says, "My name is Dilbert. Yes, I can prove it; I have a pssport and a driver's license. Well, yeah. It's easy to get a fake ID, but..." Hours later... Dilbert is still on the phone, his hair is a mess and he says, "...Okay, what if I take a DNA test? No, I can't prove I've never been cloned!!" He's angry.
Dilbert sits on the couch and Dogbert stands on the armrest. Dogbert says, "My dominion over the planet is not widely recognized by the dolts who are breathing my air." Dogbert continues, "So I've declared total sovereignty over a small, ever-widening zone surrounding my body." Dilbert asks, "How big is the zone?" Dogbert says into a megaphone, "You have just entered Dogbertland. Please show your passport and leave the oxygen alone!"
