Tristan always has the best photos. Today, he posted a link to a puzzle, the Bruegel painting, Netherlandish Proverbs. I knew it depicted various sayings, but only heard a few of them. Wiki has a fairly long, if necessarily incomplete list.
My favorite so far-
He who eats fire, shits sparks.
So many ways that would be useful. I'm going to try to revive it. Although, in English, 'farts sparks' might be easier to say.
