If by any chance you forgot that today is the craziest day of the year, you'll be reminded as soon as you open Google's homepage, where a jolly, animated Doodle is doing a disco dance.

Google has been incredibly active when it comes to Doodles this year; we've seen the regular Google logo so rarely we've almost forgotten what it looks like. Some of the best from last year were a huge interactive Doodle celebrating the first parachute jump, an epic 'Doctor Who' game and an interactive crossword puzzle.
Check out some of Google's greatest animated Doodles below.
