Angel Soft has had a page on their site up for a while now called "Bathroom Moments" featuring what they call humorous situations in the bathroom.
During a conference on e-business strategy on Tuesday in Madison, Wisconsin, this site was used as an example of "contextual marketing," the targeting of an ad to a niche group, such as parents who buy toilet paper as well as being "so catchy and relevant that you actually want to watch it again and again".
