Two things stick out in my mind. The first one is when my Aunt's Android tablet got all of its photos infected with David Hasselhoff. She didn't realize that the pictures were duplicated (so the originals were still there), so she was extremely upset that all the pictures of her late husband were photobombed with "The Hoff" (she's in her 80's, and doesn't even know what a photobomb is).

The second incident is the Google "Drop Mic" email reply button, that got accidently clicked on and caused some number of people to lose prospective business opportunities.

Now, the april fools jokes that aren't harmful are things like google maps having a pacman mode available, or when Slashdot did their "OMG Ponies" theme.

Thank you for mentioning David Hasselhoff. Until you did I didn't realize it was an April fools prank but instead thought it was a clever Google Easter Egg. My only photo with The Hoff is also one with the Queen Helen Mint Julep Mask which became a reddit mini-meme on its own. I figured some Google programmer was actually looking for people in green faces and didn't make the connection to 4/1. Thanks for clearing it up.
