The USS Quad Damage

The head of the snake

You know that guy who always makes analogies? I hate that guy...

INT. SMALL SHACK

A bearded man with a turban is seated.
Eyes full of passion. Around him are a
number of other bearded men in turbans.

BM (heavy arab accent): You must cut off
    the head of the snake! The snake will
    die at that point. This is in stark
    contrast to a worm, which will merely
    split into two worms.

WAITS FOR EFFECT, THEN CONTINUES:

BM: It is also incorrect to cut off the
    tail of the snake, which, although
    physically identical to cutting off
    the head of the snake, is conceptually
    different. Don't think the snake will
    not know! A snake with no tail will
    continue to live, but a snake with no
    head?

STARTS LAUGHING MANIACALLY.
