This'll kill it.

"What is the mark? Well the mark Brian, is the barcode. The ubitiqous barcode that you'll find on every bog roll, and every packet of johnny's and every poxie-pot pie. And every [expletive-removed] barcode is divided into two parts by three markers and those three markers are always represented by the number six. Six-six-six. Now what does it say? No one shall be able to buy or sell without that mark. And now what they're planning to do in order to eradicate all credit card fraud and in order to precipitate a totally cashless society. What they're planning to do; what they've already tested on the American troops; they're going to subcutaneously laser tattoo that mark onto your right hand or onto your forehead." (Naked, British movie, 1993, directed by Mike Leigh and starring David Thewlis)

Freaky...

"And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six."

Revelations 13:16-18

Hey, I was just talkin' about that movie in the Comments a week or so ago!

One of the formative movies of my intellectual youth. Sort of blew my mind a bit and changed what I expected from movies... more than pure entertainment, also good for the brain. And the soul.
