But then again, it is the first of April, when in 1998 Burger King introduced its Left Handed Whopper and the state of Alabama voted to change the value of the mathematical constant pi. My personal favorite happened in 2007 when Google announced a new feature of their Gmail - Gmail paper where they would send you hard copies of all your email for your safe keeping.
Or Google's "Book Search Scratch and Sniff" feature allowing users to "scratch and sniff" certain books for their smell. Users were asked to "...please place your nose near the monitor and click 'Go'." Needless to say by pressing 'Go' (or mashing it down here) they were taken to a site informing them of the Google's Annual Hoax. Good Times!
