QUOTE : When spies aren't in sewer tunnels, they're usually crawling through air ducts. I'm not sure exactly why this is. It makes you kind of wonder: Are spies just frustrated maintenance men? Is that what spies really want to be doing? Plumbing? Air conditioner repair? I fear the day that they follow their dream, lay down their laser-gun cigarette lighters, and pick up wrenches. Our country will be in great peril, though with fewer toilets backing up and more of our houses at a uniform sixty-eight degrees Fahrenheit.
