I’ve only found two so far, but surely there are more. Google is famous for their ridiculous April Fools special pages, and this year is a bit mild, but no exception. Almost an Onion-like quality to it.
EDIT: OH OH, and if you create an event in Google Calendar, it has a “I feel lucky” button. If you click it, on that day, it fills in “Date with Britney Spears” or “Date with Jessica Alba.”
How’d they know my secret schedule?
