Forget cheesy yard tombstones, evil cackling pop-up witches, or ghosts that fly down from on top of the porch. Todd Harrison has put dual 110-decibel automobile horns inside his jack-‘o-lantern, which features a cute red button nose and buck-toothed smile to throw people off from how diabolical it truly is. And here’s the really wicked part: The horn is on a delay. Pushing the button causes the eyes to light up immediately, so the little tykes think, “Hey, neat, a pumpkin with light-up eyes,” and then go on about their tyke-y business, at least for a few seconds before the dual 110-decibel automobile horns go off and leave them traumatized for life. Genius! There’s video on Todd’s site. [via Hack a Day]
