When Paris Hilton's debut album came out, Team Banksy went around to 42 different record stores and replaced her CD with Banksy remixes. The most ingenious part of this was that he totally doctored the booklet that accompanied the CD. It maintained the original barcode, but as soon as buyers opened the CD, they discovered that the original song titles had been replaced with questions like, "Why am I famous?" No one complained about the mix-up.
