This is hilarious.
Yahoo! uses Google too!?
Specifically, the Ask Yahoo! service used Google search results and forgot to change the word Google to Yahoo!
It starts here: How many countries are there in the world? – Ask Yahoo!
Notice the line
We realized the chances of finding a Yahoo! category on the subject were about as small as Andorra, but we were confident the Google search results would point us in the right direction.
MMm… someone left the word Google there?
While the link actually points to a search.yahoo.com result page.

I then went into the Internet Archive (yes, Yahoo archives the entire internet…) and looked at this Ask Yahoo! page in the past.
And I found that the “Google search results” link originally pointed to “google.yahoo.com” search results.

Strange, Yahoo used to have a google.yahoo.com subdomain …
google.yahoo.com in the past.
It used to just point to a Yahoo search page. But from 2002 onwards it just became a page with just “Do you yahoo?” on it before the subdomain was removed from yahoo in about 2003.
You can still see the “do you yahoo?” page archived here.
