RealClimate.org detailed the work of Dr. Ewe Noh-Watt of the New Zealand Institute of Veterinary Climatology, who had discovered that global warming was caused not by a buildup of carbon dioxide in the atmosphere, but rather by the decline of New Zealand's sheep population. The reasoning was that sheep are white, and therefore large numbers of sheep increased the planet's albedo (the amount of sunlight reflected back into space). As the sheep population declined, the ground absorbed more solar radiation, thus warming the planet: "It can be seen that the recent warming can be explained entirely by the decline in the New Zealand sheep population, without any need to bring in any mysterious so-called 'radiative forcing' from carbon dioxide, which doesn't affect the sunlight (hardly) anyway — unlike Sheep Albedo."

Noh-Watt also warmed of a potentially destabilizing feedback mechanism: "As climate gets warmer, there is less demand for wool sweaters and wooly underwear. Hence the sheep population tends to drop, leading to even more warming. In an extreme form, this can lead to a 'runaway sheep-albedo feedback,' which is believed to have led to the present torrid climate of Venus."

However, skeptics disputed the Sheep Albedo Hypothesis. Steve Ramsturf, spokesman for the New Zealand Sheep Farmers Guild, was quoted as saying, "Baaah, Humbug. No matter what goes wrong with the world, they're always trying to blame the poor New Zealand Sheep Farmer."

Wisconsin-based blogger Peter Hart posted a news article on the community news site WauwatosaNOW.com, claiming that the local Mayfair Mall planned to start using face recognition technology to scan for known criminals. The story fooled a reporter for WTMJ-TV who reported it as fact on the 4 pm news show.

The social networking site Facebook posted a notice about a new feature called LivePoke allowing users to "dispatch a real live person to poke a friend of your choice." The offer was said to be good for only the first 100 pokers in each network. The joke was a reference to Facebook's "poke" feature, which causes a poke icon to appear on another user's home page.

Images of an 8-inch mummified creature resembling a fairy were posted on the website of the Lebanon Circle Magik Co. Accompanying text explained how the creature had been found by a man walking his dog along an old roman road in rural Derbyshire. Word of this discovery soon spread around the internet. Bloggers excitedly speculated about whether the find was evidence of the actual existence of fairies. The Lebanon Circle website received tens of thousands of visitors and hundreds of emails. But at the end of the day, Dan Baines, the owner of the site, confessed that the fairy was a hoax. He had used his skills as a magician’s prop-maker to create the creature. Baines later reported that, despite his confession, he continued to receive numerous emails from people who refused to accept the fairy wasn’t real. He later sold the fairy to an American collector for £280.

Visitors to the search engine AskJeeves.com found the company's signature animated butler clothed in an undershirt and patterned boxer shorts instead of his usual jacket and tie. The company attributed the new look to a "wardrobe malfunction."

The Jeeves character was discontinued after 2006, and AskJeeves.com itself became Ask.com.

Bob Carroll, creator of the online Skeptic's Dictionary, announced that he was abandoning skepticism and embracing a Christian belief in divine design. He attributed his conversion to an epiphany that occurred after doing yardwork:

"I came in afterward and noticed that there were several weeds stuck to my socks and shoes. It was like a hammer to the head. I started to see the patterns. There was clearly a design here. The weeds excreted a sticky substance that allowed them to cling to my clothes. When I moved around I carried their seeds with me and had unwittingly deposited them throughout my yard. Soon, my yard would be crawling with weeds and I would have been partially to blame. But I wasn't concerned about the yard. I had a bigger problem. I had seen that randomness could not account for the weeds' behavior. Yes, behavior. What else could it be? The weeds clearly know what they are doing. They didn't just accidentally cling to me. There is no way this was just matter randomly and meaninglessly behaving in a way that looked like design. This was truly design at work."

Google announced that they were accepting applications for positions at Copernicus Center, their new "lunar hosting and research center." Applicants, Google noted, must be "capable of surviving with limited access to such modern conveniences as soy low-fat lattes, The Sopranos and a steady supply of oxygen." Google went on to say that the facility, set to open in Spring 2007, would house 35 engineers, 27,000 low cost Web servers, two massage therapists and a sushi chef.

Belief.net announced that all the major Christian denominations had jointly agreed to make Oprah Winfrey the fourth member of the Holy Trinity, thereby broadening its appeal and making it less gender-biased: "Along with the Father, Son, and Holy Spirit, the popular talk show host will be recognized as one person in the sacred and indivisible unity of the Godhead—or Quadhead, as the updated Trinity will now be called."

In response to the news, Oprah's production company issued a statement: "This just confirms what millions of Americans already know: that Oprah is a goddess—and one completely compatible with Christian faith." However, the Russian Orthodox Church had not supported the deification of Oprah, noting that "the current structure leaves no room for the possible addition of Dr. Phil."

Thinkgeek.com, an online retailer of offbeat gadgets, continued a multiyear tradition of posting fake gadgets on April 1st. This year's roster included a PC EZ-Bake Oven: "It fits in a 5 1/4" drive bay and plugs right into your power supply with the included Molex connector… The PC Ez-Bake oven can even be used to cook your Pop Tarts, Bagel Bites, or any tiny or flat food. YUM!"

The Remote Control Gastron Hunger Elimator: "Simply swallow the tiny non-digestible Gastron base station and use the remote to adjust your personal hunger level. The base station inflates to fill your stomach, giving you that satisfied full feeling with zero calories."

CaffeDerm caffeine patches: "They easily apply to your shoulder and provide a steady dose of caffeine throughout the day. These calorie-free fixes are just enough to keep you from ripping your teeth out without generating any brain fuzz so you can actually present yourself as a sentient!"

An elaborate website appeared online announcing that an Atlantic Tunnel connecting the UK and the US (and running beneath the entire width of Ireland) would be opening in September 2009: "The world is about to witness the dawn of a new era of trans-continental travel. It has taken 63 years to complete the 3261 miles of tunnel from Swansea to New Jersey. In 2009, that same journey will take passengers and their vehicles just 8 hours and 20 minutes." The site also featured a competition to win a trip on the first train through the tunnel. It's not clear who created the site, or why, but the site was registered to a London ad agency, TBWA/GGT.

The website BetterHumans.com posted news of the first case of a human catching a computer virus:

"A software developer from Houston, Texas has become the first human to contract a computer virus, microbiologists have confirmed. John Newman, an employee of vTouch Systems, came into contact with the virus through the use of a neural interface that his company is developing. Avril DuChamps, a spokesperson for vTouch Systems, confirmed yesterday at a press conference that Newman had come down with the virus. All activities at vTouch have been suspended until further notice."

Thinkgeek.com introduced the George Foreman USB iGrill, the "low-fat, high-bandwidth solution to your networked cooking needs":

In late February a Dutch company calling itself The Honest Thief announced that it would host a new, totally legal file-sharing service. It explained that it was able to do this, despite the lawsuits facing other file-sharing networks, because: "The Honest Thief is the first Dutch company to take advantage of a recent Dutch appeals court ruling that paved the way for the Netherlands to become the world's first legal haven for file sharing companies."

Large amounts of press attention followed, including an article in the Wall Street Journal. But visitors to The Honest Thief website on April 1st were met with an announcement: April Fool! There was no legal file-sharing network. The hoax was a stunt to promote a book of the same name (The Honest Thief) by Pieter Plass.

The BBC reported that school-lunch authorities in the UK had decided to ban chips (french fries) from school canteens:

Google revealed the secret at the heart of its search technology: PigeonRank. Clusters of pigeons had been trained to compute the relative values of web pages:
