My manager at work came across this version number on a document properties screen (possibly in Word?), thinking it referred to the version of software the document was written in. We bullshitted a bit about how we're still iterating on 16-yo documents, until I googled and found that it was a new MS version.
(I often find that a document I am editing at work was created by "Valued Gateway 2000 Customer")
