Your old mans version is true.Oh, you poor baby! Guess I should be thankful for this 22 degree weather I'm having.
I always used to giggle when my Old Man would say that. Ya know where it originally came from? The cannon balls on a warship were stacked in a pyramid shape on a brass/bronze frame (think cue ball rack), and the rack would shrink in freezing cold weather and the cast iron balls would fall off and get loose on the deck.
I liked pappy's version better.
