Opel has gotten into the habit of crashing Volkswagen's Wörthersee meeting and this year they managed to be a little more subtle with their "unfortunately horny" guerrilla action campaign.

In an effort to steal some thunder from Volkswagen, Opel put on a fireworks display with a hidden message. The company handed out 6,000 pairs of 3D glasses and the unsuspecting Wörthersee attendees took them assuming they were from Volkswagen. Little did they know that when they looked at the fireworks with the glasses on, they'd be treated to a colorful display of Opel logos.

Most onlookers seemed amused but a handful of fans decided to burn the glasses in a mock protest.
