“Everyone loves Gmail free email service. What ever happened to stamps, filing cabinets, and the mailman? Now with Gmail Paper, you can request a physical copy of any message with the click of a button, and it’ll be sent to you in the mail. Photo attachments are printed on high-quality, glossy photo paper, and secured to your Gmail Paper with a paper clip. And it’s totally free: the cost of postage is offset with the help of relevant, targeted, unobtrusive advertisements printed on the back of every print.”
I dunno, I think Gmail was the ultimate April Fools Day hoax because it really turned out to be real, but nobody believed it until after April Fools Day was over because it sounded so implausible.
