"In August/September 2006, Banksy replaced 500 copies of Paris Hilton's debut album in 48 different UK record stores with his own parodical remixes and cover art. Music tracks were given titles such as 'Why am I Famous?', 'What Have I Done?' and 'What Am I For?' The cover art depicted Paris Hilton digitally altered to appear topless. Other pictures feature her with a dog's head replacing her own, and one of her stepping out of a luxury car, edited to include a group of homeless people, which included the caption '90% of success is just showing up.'"
