Just a few things about the insane American tradition called "Black Friday" where everybody seems to go crazy beyond all levels:
CHEEZburger has a great summary of this insanity as well.
And probably my all-time-favourite piece of art about Black Friday comes from Southpark: Southpark Season 17 Episode 7 "Black Friday" and Episode 8 "A Song of Ass and Fire". Absolutely worth watching!
