War of the Satellites1958

Sybil Carrington:
[reading a message sent to Earth] To the United Nations of the third planet of minor luminary Sol, called by the inhabitants thereof the Earth, Attention. We the masters of the Spiral Nebula Ghana have been observing your actions. Understand, earthlings, that we look with disfavor upon your persistent efforts to depart from your own planet and infest other areas of the universe. We have therefore set up quarantine measures to ensure that this contamination shall not be allowed to spread. We shall frustrate your every attempt in the future, as we have those in the past. Knowing that earthlings are equipped with rudimentary reflex-type intelligence, we are taking this means of conveying our command that all such efforts to expand and depart from the infected planet Earth shall from this moment be stopped.
