Dogbert and Dilbert walk through the park. Dilbert says, "Nature is so wonderful . . ." Dilbert continues, "They say we don't leave the planet to future generations, we borrow it from our children." Dogbert says, "It's even better than that." Dogbert continues, "WE don't have children, so we're borrowing the planet from complete strangers!" Dogbert continues, "And there's no collateral. We can use up the planet, have great lives and leave an empty smoking shell to the strangers!" Dogbert continues, "I tell you, people have completely overlooked the positive side of this environment situation." Dilbert says, "But someday I WANT to have children." Dogbert replies, "Let's hope they're not as selfish as you."
