From the December 15, 1909 Watchtower:
"While our faith and hopes would be equally clear and logical whether this age ends in October, 1914, or a century later, nevertheless our expectation that "Gentile Times" will conclude October, 1914, undoubtedly has a stimulating effect upon our hearts and influences all of life's interests and helps to "wean" us from earthly joys and ambitions and to set our affections on things above!" [Italics mine]
Wiggly bastards, aren't they?
