That was typically how I heard it used, too. Couldn't tell you when I last heard it uttered, though. Decades back, probably. A few of 'em. As to the "all the tea in China" ... That also meant an almost unfathomable amount, used in phrases such as "I wouldn't [fill in the blank] for all the tea in China." And then there was the phrase "What does that have to do with the price of tea in China?" which of course has an altogether different meaning.
