April Fools!

Google and Topeka, Kansas, Switch Places

In early March, the city of Topeka, Kansas, temporarily changed its name to Google in an attempt to capture a spot in Google's new broadband/fiber-optics project. Then, on April 1 (April Fools' Day), Google jokingly announced that it would be changing its name to Topeka, to "honor that moving gesture" and changed its home page to say Topeka in place of the Google logo.
