Companies were cashing in on April Fools' day with a slew of creative products, new website designs and videos.

Google extended a tradition dating back a decade or so, in poking fun at its own ubiquity, introducing a database of smells aptly named Google Nose and revealing that YouTube was one big contest and they are finally shutting down entries.

Procter and Gamble's mouthwash brand Scope offered a new flavour - bacon, "For breath that sizzles."

Virgin Atlantic chief Richard Branson got in on the fun, unveiling a new airplane with a glass bottom. On the company's blog he posted pictures of the newly designed aircraft and renderings of the new plane.

Netflix was a little more subtle in its website tweaks. They added in overly specific categories to their video browsing page including "Movies starring actors who look like Zach Galifianakis."

Video upload site cashed in on the cat video craze and renamed themselves "Vimeow" for the day, featuring all types of cat videos on their home page.

And not to be outdone, late night talk show host and comedian Conan O'Brien announced the creation of an online college named Conan State University. He said in a video that the sole purpose of creating the school was to be able to cash in on the March Madness basketball tournament craze.

Even the White House got in on the fun, with the help of nine-year old YouTube sensation known as Kid President. It started with a tweet from the White House announcing a "special video message from the President". Viewers who tuned into the White House website to listen to the president were taken to a video that opened with the familiar shot of the White House briefing room typically used by spokesperson Jay Carney, and sometimes President Barack Obama himself, to address the White House press. Kid President, whose real name is Robby Novak, then rises from behind the podium to tell viewers they've been pranked.
