Gmail Custom Timehttp://mail.google.com/mail/help/customtime/

From those tirelessly innovative geniuses at Google comes a feature to backdate your e-mail so it looks like you sent it hours, days or even weeks earlier, getting you off the hook with whoever is angry with you for being late. "I used to be an honest person; but now I don't have to be," writes one satisfied customer. "It's just so much easier this way."

Google also announced it was partnering with Richard Branson's Virgin Group to establish the first human colony on Mars by the middle of the next decade. "Earth has issues, and it's time humanity got started on a Plan B," states the Web site, which also features a video greeting by Google founders Sergey Brin and Larry Page and an online application for interested Martian colonists.

Apple Logo Makes You More Creativehttp://news.duke.edu/2008/03/apple_ibm.html

Duke University released details of a study that determined people were more creative about ways to use a brick after subliminal exposure to Apple's ubiquitous logo than they were after briefly viewing the IBM logo. This one might actually be real, since the Duke press release is from March 18, though the study is being published in the April issue of the Journal of Consumer Research.

Facebook App Helps You Spy on Your Spousehttp://technology.timesonline.co.uk/tol/news/tech_and_web/article3656103.ece

Another one that may be true comes from the Times of London, which reports on Sniff, a Facebook application already in use in Scandinavia that tells you exactly where your friends and loved ones are by using cell-tower triangulation to locate their mobile phones. The company behind it appears to actually exist, and there's a page on Facebook that offers sign-ups for when the service expands to the rest of the world.

Wi-Fi Radiation Makes Teacher's Head Explodehttp://www.theregister.co.uk/2008/04/01/teacher_head_explosion/

One that's definitely not real is a story from Britain's tech-news site the Register, which lampoons British press hysteria over the dangers of wireless networking in schools. "A middle-aged sociology teacher's head was actually caused to explode by a combination of Wi-Fi transmissions, deadly mobile phone radiation from pupils texting in class, and emissions from a nearby TETRA mast," states the story. "'It just blew up, man, like a dog in a microwave,' said a shocked pupil."

Modern Computers Are for Newbieshttp://www.pcmag.com/article2/0,2817,2280375,00.asp

PC Magazine editor Lance Ulanoff, a frequent guest on FOX News Channel, confesses his deepest, darkest secret — his primary machine is a 1991-vintage Compaq with a 33-Mhz processor running Windows 3.1. "The 256-color operating system happily coexists with my 5.25- and 3.5-inch floppy disks and, more importantly, with my all-time favorite word processor, XyWrite III," Ulanoff defiantly declares.

Embattled Wikipedia Founder Becomes a Monkhttp://www.theregister.co.uk/2008/04/01/jimmy_wales_resigns_from_wikipedia/

The Register has fun with one of its chief targets for mockery, embarrassment-plagued Wikipedia top man Jimmy Wales, whose ill-fated dalliance with a Canadian conservative blogger ended with her putting his discarded clothes up for sale on eBay and allegations of expense-account padding. "With the help of renunciates from across the globe, I plan to record the sum of all human knowledge on stone tablets," the Register says Wales told them in his announcement that he would join a Franciscan order and take "the traditional vows of poverty, celibacy and obedience."

Colombia Draws 'Cocaine Tourists'http://www.guardian.co.uk/travel/2008/apr/01/colombia.southamerica

Again, another British newspaper article that may even be true, ths one from the Guardian. It states that Bogota has replaced Amsterdam as the drug-seeking backpacker's destination of choice as bored young Westerners flock to Colombia to sample its most famous product. "2, 4, 6, 8, who do we appreciate? Cocaine!" one unnamed Englishman is quoted.

The London Sun, the most entertaining newspaper in the English language, reports that Israeli researcher "Ura Schmuck" plans to use "Stature Augmentation Treatment" to stretch out notably wee French President Nicolas Sarkozy so that he will be taller than his Italian supermodel wife Carla Bruni. French government spokesman "Luc Biggér" said the difficult process would be carried out at the "the Poisson D'Avril Medical Centre in Geneva."

Geek Sillinesshttp://www.thinkgeek.com/

Online tech-toy retailer ThinkGeek has a field day with dozens of phony gadgets, ranging from Spazztroids Caffeinated Breakfast Cereal to a USB pregnancy test to the Super Pii Pii Brothers urinating game for the Nintendo Wii, complete with custom Wii Remote adapter. Our favorite? The Betamax-to-HD DVD Converter, which allows you to move movies and TV shows off one obsolete video format and onto another.

Rollin', Rollin' on the Rick Astleyhttp://www.youtube.com/

Now that The New The York The Times has noticed the year-old Web phenomenon known as "Rickrolling," YouTube celebrates by linking every single one of the "Featured Videos" on its front page to the same clip of the '80s crooner doing "Never Gonna Give You Up." We here at FOXNews.com hope this finally puts an end to this tired meme so that the hollow-eyed late-night Web herd can move on to something else.

All the News That Fits to Shrinkhttp://www.news.com/

Venerable tech-news site News.com has breaking stories today — top Silicon Valley blog Tech Crunch is buying teen mag Tiger Beat and Facebook founder and head post-adolescent Mark Zuckerberg will host "Saturday Night Live." Best of all is a report on rampant sniping on spy-data repository Intellipedia, where Vice President Dick Cheney and CIA head Michael Hayden exchange words over which is the best "Buffy the Vampire Slayer" episode.
