This, of course, is the famous command from The Day The Earth Stood Still. It loosely translates to "Gort, stop!" Gort being the lead alien who was hell bent on taking over the world. If I’m not mistaken, I believe Gort means George in English.
I saw this movie when I was 8 or 9 years old and I remember being scared out of my wits. I couldn’t sleep for fear of Gort’s jaws opening and the death ray shooting out from it. I memorized the words "Klaatu barada nikto" and would go around repeating it over and over again, terrified I’d forget it right at the moment I’d actually need it. A drama queen at 8. Scary.
I was also absolutely terrified of Reddy Kilowatt. 
I would lie awake at night, fixated on the electrical outlet across the room from my bed. I KNEW Reddy was in there, waiting until I fell asleep before he’d come out and dance on my chest. It’s a wonder I ever got any sleep at all. Or that I’m not in therapy.
Living in Costa Rica, I sleep great! I’m not terrified of anything. Er, much. Sadly, as a U.S. citizen, I’ve been too trained for too long to not find something to terrify me. Today’s terror fix came thru in this scary little short from the MSM: The Day King George Was Crowned. Should make for some sleepless nights.
All together now: "GORT, KLAATU BARADA NIKTO!!!!" (Or, in English: "GEORGE, STOP!!!") There. That should do it. It helps being 3000 miles away, let me tell you.
Wow! Where did you grow up? I never heard of this stuff but then I never heard of most fairy tales either until I was half grown. My Mom believed in reading Bible Stories, we had volumes! (Baptist)
I grew up in KY. Watching TV, of course!!! That’s where I got my real education… sure didn’t get it from the schools or church. Although I was a “Jesus freak” in high school, was baptized in the Central Baptist church – practically holy rollers. That was fun. My boyfriend and I would go parking, do everything BUT “it”, then we’d pray for forgiveness. All a necessary part of the drama development. Sigh.
