I don’t like those Google ads that come up when you’re searching for some specific book and lead you to ebay or somewhere like that, where they tell you they haven’t got it. But the following is amusing: it appeared when I was looking at the law section of the Times Online
bq. Legal Profession Sale
New & used Legal Profession Check out the deals now!
It did produce a lot of Buy It Now ads, mainly for books, but no sale of The Legal Profession as such.
