From the good book:

And he struck forth, and his wrath did cleave the offender's blade in twain with a flash of light and roar of thunder. The crowds receeded and fell silent, awed and terrified by the presence of the great one. And with the voice of a vengeful god, these words spake he: "This, is my boomstick!" -Necronomicon, Book of Ash, 3:14
