In a series of tweets Friday morning, Oculus co-founder Nate Mitchell revealed that Facebook accidentally included some secret 'joke' messages on the internal components of tens of thousands of Touch controllers.

'This Space For Rent' and 'The Masons Were Here' were printed on the innards of the controllers' final production hardware. A few developer kits shipped with 'Big Brother is Watching' and 'Hi iFixit! We See You!' messages as well, but those were limited to non-consumer units according Mitchell.
