HeadOn was a topical headache product sold in the United States, and its low budget television commercial first gained wide attention in 2006. Instead of explaining the product, the ad simply repeated its slogan three times while a woman applied it to her forehead. The strange, relentless format was widely parodied on late night television, in online videos and in remixes, turning an ordinary ad into a lasting meme. It is still used whenever creators need a instantly recognisable reference to headaches, intrusive thoughts or something repeating until it becomes funny.
