Today's Best April Fool's Stories Twitter, Google, and Virgin roll out doozeys By Neal Colgrass, Newser Staff Posted Apr 1, 2013 7:30 PM CDT 3 comments Comments Virgin Group's design for a "glass-bottomed" plane. (Virgin.com) (Newser) – You may have seen Google's plan to "shut down YouTube," but that wasn't the only media-perpetrated April Fool's prank today, CNN reports. Among the day's best: Twitter (sorry, "Twttr") announced that vowels are no longer permitted in tweets, so as to facilitate a "more efficient, and 'dense' form of communication." Virgin Group founder Robert Branson said he would release the world's first glass-bottomed plane to coincide with the company's first flights to beautiful Scotland—ideal for "natural born explorers." The left-leaning Guardian newspaper unveiled Guardian Goggles, designed to help users "see the world through the Guardian's eyes at all times." It comes with "optional built-in anti-bigotry technology." Archaeologists digging beneath Stockholm "were stunned to find" Thor's hammer, The Local reports. Choice quote from an Norse mythology "expert": "It's easy for us scientists to slip into atheism by some kind of default, a work hazard of sorts, but I have no idea how to explain this." The Daily Mail reports on new "50 Shades of Grey" toilet paper, with each shade named after a lead character. "Much like Grey’s character all rolls are tightly wound and will take time to unravel," said a rep. Click for the Guardian's many candidates or see last year's roundup of April Fool's ads.
