Google has hidden another Easter Egg in its search results. Googling “Zerg rush” transforms the search results page into a game where your search results are being attacked by a swarm of O’s.

If you fail to stop them, your search results will be consumed by the hungry O’s. More after the break.

Everybody knows that Bing doesn’t hold a candle in front of Google in terms of users therefore it’s not surprising the Bing team has been caught copying and correcting top misspelled search terms, with data mined from Google’s results.

The blog Search Engine Land uses the example of “torsoraphy,” which Google corrects to the correct spelling of “tarsorrhaphy” and brings up relevant search results for that term.
