Hasn't anything else ever happened on June 6?

Google has a practice of redesigning its portal page (google.com) on certain days to reflect the theme of that day.  For example, on Valentine's Day "google" will be spelled in pink letters surrounded by hearts, on Christmas the page will be green and red, etc.  I just turned to the home page to find that apparently Google is today honoring the 25th anniversary of Tetris.  I shrugged and figured that it must be a slow day for anniversaries, but then I suddenly remembered that today is also the 65th anniversary of a rather more important historical event.  To be fair, that particular event has never come to the attention of the idiots who run Google, since it doesn't get discussed on The Hills.
