I know this is just my particular country, but I will wish you a Happy Fourth of July Day! Or as I affectionately call it, "Happy Drink Beer and Blow Sh*t Up Day".
Though, I think that the announcement from C.E.R.N. labs that the Higgs Bosen is real today is just kinda more awesome. Smash atoms together to create tiny black holes? Man, it doesn't get any more bad ass than that.
