““Perhaps one night, when you were very small, someone tucked you into bed and read you a story called "The Little Engine That Could," and if so then you have my profound sympathies, as it is one of the most tedious stories on Earth. The story probably put you right to sleep, which is the reason it is read to children, so I will remind you that the story involves the engine of a train that for some reason has the ability to think and talk.””
