Alan, it was re-posted/re-copied/re-pasted/re-submitted so many times from one web-site to another web-site,

that the denominator was lost long time ago,  but nobody of these re-translating people knows and nobody of them 

notices or understands it of those who re-copy,  re-paste and re-submit, producing and spreading tons of garbage 

in the  Internet.
