Out of all the comics I've made, I may very well have been emailed more about this one than any other. Well, technically, the emails are more about what I say about this comic.
You see, I usually credit the Author's line in the second panel to the cult-horror-comedy classic, Army of Darkness, the sequel to Evil Dead and Evil Dead II. But, as the emails all point out, the original line comes from The Day the Earth Stood Still, where it's used to control the robot Klaatu.
The problem is that not only have I never seen original The Day the Earth Stood Still, but the idea of using the words as part of a magic spell, especially to resurrect the dead, are directly from the Sam Raimi film, which is why I say that's where the allusion lies. So, if anything, it's a second-hand allusion.
As far as the spelling, the best I could do was go with the spelling from The Lost Vikings II, in which a witch unsuccessfully tries to use variations of the spell to send the vikings home.
