When I was a young'un when we looked in a box for cookies or something and there were none we would say "Ain't nary'n". Then when I went to school my teacher said that ain't and nary'n are both negatives. Now we had learned in algebra that 2 negatives equal a positive. That would mean that there actually at least one cookie or whatever. Well now 3 negatives equals a negative. I had to start saying "Ain't not nary'n". Teacher said that would work just fine.
