This is a pretty entertaining April Fools joke from Google. There was a link to this new service from Google's homepage today. It is the TiSP (Toilet Internet Service Provider), which provides free in-home wireless broadband service through the sewage system. If you sign up for this service you receive an installation kit complete with rubber gloves and a spindle of fiber optic cable. Install instructions include 'Attach the sinker to the loose end of the cable, take one safe step backward and drop this weighted end into your toilet.' and 'Grasp both ends of the spindle firmly while a friend or loved one flushes, thus activating the patented GFlush system, which sends the weighted cable surfing through the plumbing system to one of the thousands of TiSP Access Nodes.' Read the full install instructions here. I like it when large companies are able to keep their sense of humor.
