1748 Bull S

Bulls seem to run rampant through our culture. Or at least our metaphorical culture. And when they aren't being used as metaphors, like for the mood of the stock market or something, they seem to function well as similes as well.
Like not long ago I was reading an article on how the Chinese media saw the American treatment of a Chinese dissident. We had sheltered him briefly in our embassy in Beijing and caused a bit of a diplomatic crisis. A Chinese commentator apparently said, in Chinese, that it was a reflection of American diplomacy generally and it's indicative of how we throw our weight around "...clattering around Asia like a bull in a porcelain factory."
"Like a bull in a porcelain factory." Wow, isn't it amazing how close that sounds to, "like a bull in a china shop." An astonishingly similar simile. Or in this case, since it's Chinese, an astonishingly similar Sino-simile.
This must be one of those primitive concepts that evolved in different cultures in the same way. The rowdiness of a bull and the delicacy of pottery.
"Ugh, like bull mammoth in place we make clay bowls."
A proto-simile if you will.
I heard another bull reference recently in a commercial for an insurance company. They were using alliterations. In this case with the letter B. And they said as one of them, "...and that's no B.S.?"
Did I miss something here? Has B.S. now landed in the pasture of acceptability on the public airwaves? And if I were an insurance company, hoping to appeal to a broad spectrum of sensibilities, would I fling it around indiscriminately?
Not a word to bulldoze through Emily Post's china shop of social etiquette, I'm sure.
America, ya gotta love it.
