... No Shit! | Sprachlog. (Hat tip, Dave Lull.)
I found this particularly interesting: "Dundes claims that German farmers (but not farmers in other cultures) used to keep a manure pile in the back yard, to be used as fertilizer (p. 12ff.)."
Professor Dundes apparently knew little of gardening. I have a com poster in my own backyard. I'm not German, and I live in the city. I always thought this canard had something to do with Martin Luther's predilection for scatology. Shows you what I know.
