Google's April Fool's joke for this year—a lunar datacenter—is hilarious. I don't think Gmail is a joke, though.
[UPDATE: On a subsequent page in the joke, it describes the complex: "The Googlunaplex will house 35 engineers, 27,000 low cost web servers, 2 massage therapists and a sushi chef formerly employed by the pop group Hanson." Priceless!]
