Cock Fight: If you think you’ve seen or heard it all then check this out: How about a video game targeted to teenagers to prevent the spread of HIV? Forget using a control—all you need is your penis. Confused? I’ll let AIDS organization (and this game concept’s creator) Don’t Forget AIDS, e.V. explain this one:
"Cock Out: an online game that takes a literal approach to the fight against HIV. The user takes part in a virtual boxing match against the diabolical human immunodeficiency virus. What makes this game so unique is that it’s not played using a keyboard or joystick, but instead with the user’s penis — inside a special condom.
A marker on the condom packaging allows the user to access the game. The webcam detects the horizontal movements of the red condom on the player’s penis. The game’s features include a choice between three penis fighters, two hosts who ensure player “endurance” between rounds and a function that allows users to share their high scores on Facebook. Launched on World AIDS Day, the game was advertised using a TV ad, posters, flyers, viral films, banners, social networking sites and a condom distribution promotion.”
This takes the saying “rock out with your cock out” to a literal sense.
