Rather than try and fool you, Google today have decided to treat you to an arcade throwback that you can play right in your backyard, and all you have to do is go to any Google map on your browser and hit the Pacman option in the bottom left corner.
Above is Dublin's St. Stephen's Green Pacman-ified, an that there below is the interior of Trinity College Dublin taken over by Pacman and his Ghost enemies Blinky, Inky, Pinky, and Clyde, which is a lot of fun and will make for some good procrastination as you avoid all the other ridiculous April Fool's Day jokes (but take our advise and don't use a map with roundabouts or curves, it gets very frustrating).
This just goes to show you that, like Tetris, if someone puts a free game of Pacman in front of you, you will play it (until you make a stupid mistake thanks to a dodgy joystick/controller and end up dying on the first level and then rage quit).
