It's one I've never heard before. (I certainly like it a whole lot better than the wife beating falacy.) Before thermometers were invented, brewers would dip a thumb or finger into the mix to find the right temperature for adding yeast. Too cold, and the yeast wouldn't grow. Too hot, and the yeast would die. This thumb in the beer is where we get the phrase "rule of thumb". Rima
