Think the Bang Bus is the dirtiest thing on six wheels? Well, this ad campaign for All Small and Mighty brings the competition with their bus full of dirty clothes driving around New York City.

And there is some sort of shopping spree contest for people who spot this dirty ol' bus. So if you see it, make sure you text you sighting before you run home and try to wash your closet with one little bottle of detergent. Advertising and promotions are just getting so creative these days.
