On This Day

I have an iGoogle homepage with one of those "On this day in history..." windows

It has all the normal stuff, like today is:
Michael Jackson's birthday (1958)
the last public concert performed by the Beatles (1966)
Ingrid Bergman's birthday (1915)
the 3rd anniversary of Hurricane Katrina hitting New Orleans
Oliver Wendell Holmes Sr's birthday (1809)
the day that a star in Cygnus went nova? (1975)

But the ones that I truly, truly love are:
Saruman enters the Shire
Skynet becomes self-aware (1997)
