In Reply to: If stands stiff... posted by Glyn Carroway on October 10, 2009 at 08:46:
: During a family discussion yesterday someone said "Pigs might fly" in response to a fairly unlikely situation. My mother, who is 90 years old, came back with "If stands stiff in every man's pocket"! I was amazed because I have never heard her say this before and I wondered where the saying originated.
