Google sure nose how to pull a good April Fools' Day prank. And The Google doesn't just stick to one form of tom foolery; oftentimes there are several pranks floating about for people to find.
One such prank for 2013 April fools is Google Nose (in beta). They're calling it "the new scentsation of search." You know how I love a good pun :)
