Who probably learned it from other textbooks who were written by other professors, who heard about it from other professors that also got it passed on to them by someone who thought it was funny.
Textbooks can be wrong and most don't go to the liberty of citing sources (anyone can write a book, just as much as anyone can write a website). Marketing textbooks that use the Nova as an example just seem to be perpetuating a popular urban legend just to try to make a (humours) point.
Snopes on the other hand, one of the best sites that go through the effort of using primary and secondary sources to either verify or debunk claims, actually has cited references. Unfortunately, I can't go chasing up these sources... can be a bit hard to access them at times, but lets take the benefit of the doubt with the seemingly more reputable party
Also, I don't know why I bothered writing about this... hmmm.
