The one by drawfloat?

Looking at the source of the cached page,

https://webcache.googleusercontent.com/search?q=cache:sRJX_e...

It contains

       <a href="/quotes/tag/don-t-give-up-quotes">don-t-give-up-quotes</a>,
       <a href="/quotes/tag/don-t-give-up-the-fight">don-t-give-up-the-fight</a>,

After you eliminate HTML, that becomes "don-t-give-up-quotes, don-t-give-up-the-fight" and since punctuation is stripped, that matches.

Full disclosure I work at Google, but not on Search.
