Love teasing your fellow cubicle mates at the office? How about scaring the pants of those who are weak-hearted and yet work late into the night all alone? The Eviltron from ThinkGeek fits the bill berfectly.

This fiendishly small device features six creepy sound choices perfect for frightening your “friends” and co-workers. Simply choose your favorite sound (or use the random mode), place it in a dark hiding spot and watch the madness begin. Perfectly suitable for dorm, office and home use. Or try putting it in someone’s car – that gets them every time.

Among the sounds available include some unsettling creaking, unidentifiable scratching sounds, gasping last breaths, a sinister child laughing and an eerie whisper of “Hey, can you hear me?” – turn on the Random Mode if you’re going to have some real fun. Retailing for $9.99 each, it will be able to last for slightly more than a month of continuous use.
