Google's Fools Day Prank

Well,all of a sudden Google declared it is giving ad supported free internet through your Toilet Room.This press statement is really hilarious and it doesn't take much time to know it's a fool's day prank and Google is not new to this.They are telling users who ever signs up for the service will receive a full home self-installation kit, which includes a spindle of fiber-optic cable, a TiSP wireless router, installation CD and setup guide.
Some silly clues to you find the truth.

Why do Google need toilet to connect to net when they can do it through underground cabling or some Wi-Max kind???

What about Google's ambitious San Francisco-wide free wi-fi project???They never told it'll be Toilet project???

They didn't mention Geographical location where they will implement??

Anyway enjoy the prank.
