I thought this was awesome when I stumbled upon it- try to register for it and gives you a cute 404 type page with other 'failed' April Fool's funnies. Like 'Google Romance (beta)'.
Someone had to have gotten the idea from a Dilbert comic I have posted in my cube at work. Pointy haired boss comes up to Wally and says something like, "our competitors just found a way to send broadband traffic over the power grid. I want you to find a way to send it through the sewer system." Then the last image shows Wally walking into the Men's room with a newspaper under his arm thinking, "I thought I was already doing that."
