You haven’t heard about the Martian invasion of 2040?
Tsk, tsk. What do they teach children nowadays? Well,
you know, the invasion never really happened, because
a single book stopped it. What was the book, you ask?
A noble encyclopedia? A tome about rockets and
missiles? A secret file from outer space? No, it was
none of those. It was — but here, let me turn on the
historiscope and show you what happened many
centuries ago, in 2040. (She turns on projector, and

powerful and intelligent creature in the whole

THINK-TANK : That’s better, Noodle. I wish to be placed in
communication with our manned space probe to that
ridiculous little planet we are going to put under our
generous rulership. What do they call it, again?
