I used to think "bull in a china shop" was "bowl in a china shop." Which made me wonder, wouldn't a store that sells place settings actually WANT bowls in the shop?
To which the Livejournal's owner replies: Ha! Even funnier was that when I read that, I was thinking "hmm, it WOULD be dangerous to bowl in a china shop" but you meant bowl as a NOUN!
