If you have both cats and dirt you may want to be wary of a new type of worm that's infecting computers across Great Britain -- or computer, anyway. It's called an earthworm, and one of the five-inch variety stealthily found its way into the laptop of one Mark Taylor. He began receiving overheating errors and took his machine to a technician who promptly found the unfortunate invertebrate wedged in the cooling fan, slowly crisping thanks to the system's heat. Taylor thinks one of his cats dug up the worm, brought it inside, and then the poor thing crawled through one of the cooling vents on his notebook to flee its pursuer. We're not sure how it got separated from its ultra-high-tech-indestructible-super-space-cyber-suit, but surely somewhere Queen Slug-for-a-Butt is laughing.[Via Switched
