I came across this link while doing some research on "Nudge" earlier this week and got a kick out of it.

Its an ad for a violent video game depicting mothers watching a trailer in complete disgust... at the end of the ad it lists a website URL www.yourmomhatesthis.com which takes you to the video game publisher.

Heres the URL to the ad http://www.youtube.com/watch?v=nKkPFDEiC6Q

..and www.yourmomhatesthis.com

Not really sure what the game is about, but it the ad seems to effectively use behavior economics to influence consumers.

Also a neat quote from John Kenny, author of "Marketing to Crazy People," an interactive guide to behavioral marketing..."For guys the best way to persuade them that a video game is cool is to tell them their mom hates it. Really simple insight, but that’s the power of behavioral economics...."
