After the many years we have spent our hard earned dollars on Nike sweat suits and sneakers, we still have absolutely no idea what "Just Do It" actually means. Nonetheless, the shoe company has managed to successfully associate the catch phrase with several iconic products over the years with equally epic ad campaigns.

Case in point: Gossip Girl cutie Taylor Momsen's viral video for Nike. In the clip, the actress is suppose to be hawking sports bras and shoes. However, after all of the super swift martial arts moves Momsen performs, while trying to escape the crowd of paps, we could have sworn it was in reality a one-minute short for an upcoming Billy Blanks project. Watch and enjoy.
