Shell recently held a public ad contest, inviting contributors to add their own slogans to the images of nature that Shell provided. The internet was more than happy to oblige.
Update: It appears the ad campaign was actually a clever ruse by The Yes Men and Greenpeace. Despite the impact such a realistic spoof could have, Shell has said they will not sue.
