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 a film called The Day the Earth Stood Still, where it's used to control a robot.
The problem is that not only have I never seen 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 tries to unsuccessfully uses variations of the spell to send the vikings home.
