Want to venture a guess? The person that guesses first or comes closest wins a free one! Good luck! And like we have to say, NO, employees are not eligible to enter or win because you already know what it is, duh.
UPDATE: Ok either we made the contest way too easy, or you people are super smart. Well, you are geeks after all, so your collective IQs are clearly above average. The secret product is the Dismember-Me Plush Zombie - a product invented by the monkeys at ThinkGeek.
Anyhoo, the big winner is @etherknight! YAY for you! We'll contact you through the bat phone (ok, via the email address on your account) to get you your free Zombie. Congrats ethernight and to everybody who figured out what it was. We'll make it harder next time, promise!
