@sundogplanets Many French phrases with cows, most of them unflatteting (for the cows, I mean).
"To talk like a spanish cow" -> to be unable to talk properly (probably "basque espagnol" was transmuted into "vache espagnole")
We don't say "pigs", but "cows" for cops (this one comes from German : Wache -> vache). Lots of "death to the cows" graffiti around.
