From “Hills of Death”, episode six of the 1951 Republic Serial Radar Men From the Moon:
Graber and his henchman return to Krog’s cave hideout after escaping from Commando Cody. They’ve spent the past three episodes (unsuccessfully) trying to get money so that their employers, prospective invaders from the moon, can continue to finance their campaign of terror. As they give Krog the stolen payroll, a message comes over the radio.
Redik: Redik calling Krog. Redik calling Krog.
Krog: Yes, your excellency. I was about to call you to report that we’re just about to put our ray gun into operation again.
Redik: I have another mission for you first. Do you have an atomic bomb strong enough to start a volcanic eruption in the Mount Alta crater?
Krog: Yes, but an eruption in that mountainous area would do very little damage.
Redik: On the contrary! It will do a great deal of damage. The present atmospheric conditions on Earth indicate that an eruption would cause torrential rains, and the resulting floods should seriously disrupt transportation and defense measures.
Krog: Excellent idea. We shall carry it out at once.
Redik: Very well. Then start an intensified campaign with the ray gun. Earth’s defenses must be completely broken down before we can risk an invasion from the moon.
Krog: Yes, your excellency. [to Graber:] You heard the orders: charter a plane and drop one of our atomic bombs into the Alta crater. Nature will do the rest.
Graber: Okay. When do we do it?
Krog: At once! I will get you the bomb. [He gets a box from beneath his workbench, and pulls out an atomic bomb. He hands it to Graber.]
YOU are the lowest form.
YOU can’t procreate alone.
YOU destroyed the village.
YOU don’t know the Truth.
YOU are educated stupid.
YOU are your own poison.
YOU worship cubeless word.
