Always, eager for a good opportunity to laugh, Google launched a number of April Fool’s Day jokes on April 1st this year. My personal favorite was a stunt they pulled at Google.com.au (Australia) offering a new feature titled gDay™ with MATE™, allowing you to search into the future.
gDay wasn’t the only prank Google pulled, their largest was a collaboration with Virgin Media, titled Virgle, looking for pioneers for their expedition to colonize Mars. With a company as big and innovative as Google this sort of endeavor is semi believable and probably threw quite a few people for a loop.
Google also added a couple other features worthy of a laugh, Gmail Custom Time, allowing users to send messages back in time, and Google Wake-up Kit, complete with a bucket for cold water and a bed flipper.
