Reminds me of a story I read in the apocryphal tales section of the guardian.

A couple were on holiday on one of the mediterranean islands and on their return to the hotel room, found it ransacked, fearing a burglary they checked to see what was missing - nothing was gone, not even the camera ( an easily saleable item)so they carried on with their holiday and forgot about it. On returning to UK they had their photo's developed and there were all the places they recognised,all the faces they recognised, and two backsides they did not recognise protruding from which were two toothbrushes they did recognise.
