Can we get some older citations?Edit
While the citation from 2007 shows the meaning of the phrase, it doesn't show the history. A small amount of web searching turns up a lot of people asking where it comes from, usually under the impression that it's from the twentieth century or later (e.g., one prominent question on Yahoo answers asks, "What movie does this come from?"). In fact, it's much older. Just for example, a little more digging shows that phrases.org.uk has a citation from Bartlett's quoting a Robert Burns poem from the eighteenth century. It would be kind of nice to get a couple of older citations listed here.
