In 2005, Sony BMG released a 3-CD set entitled Electric 80s. The cover art for this compilation featured a reproduction of a UPC bar code, with the title "ELECTRIC 80s" placed in the space at the bottom of the bar code where the human-readable numbers corresponding to that code would usually appear. ... Unfortunately for some retailers, the machine-readable version of the bar code used for the CD compilation's cover art was scannable by their systems.

Note, the only reason I'm passing this on as true is because snopes.com says it is, and I trust that being an urban myth debunking site, they actually check that news items really happened. 'Cos I haven't seen this in any .uk-ish newspapers.
