A man, only known as 'Banksy' is a very popular troublemaker from London, England. He is known for pulling pranks on the public, as well as spray painting elaborate pictures on public buildings, often containing a message of protest.
On the release date on one of Paris Hilton's albums, Banksy casually walked into 48 different stores, and swapped 500 of the original discs with his 'new and improved' remixed version. The picture on the CD was that of Paris Hilton naked, with her faced swapped out for her very own dog's.
Banksy's CD featured songs titled "Why am I famous?" "What have I done?" And "What am I for?". Banksy opened up the cases and swapped the CD's out, keeping the original barcode on the case of the CD, so that nobody knew they were purchasing a CD that was remixed.
In response to the pranks, a spokesman for Virgin Megastores said "I have to take my hat off - it's a very good stunt" because it took a considerable amount of time for employees to find which CD's were Banksy's remixes!
