"Rule of the Caravan Wastes: Do not fuck with the man who delivers your mail."
— Cass, Fallout: New Vegas
"So, do you deliver your own mail, or do you have your own mailperson? But then, who delivers his mail? Is there a never-ending chain of mailmen delivering mail to other mailmen? Well, I guess a P.O. box could, in theory, break the chain."
— SpongeBob SquarePants, SpongeBob SquarePants, "Procrastination"
