Olympus devil babies
An ad rejected by Olympus (presumably for giving them all weeks of bedwetting nightmares) has become... well, "viral" probably isn't correct.. hard to tell with such an abused (notably by us) term, but the ad is "popular with the kids", let's say. Funny ad, at any rate. Dark for such a mainstream product and company. We link to Ad Land who offer the clip and expound a bit.
