Conspiracy

A caller to Rush Limbaugh's radio program yesterday offered this, the mother of all conspiracy theories:

Nixon and Reagan, both in the pockets of Big Oil, conspired to assassinate John Lennon because he was the only one who had the power to stop the current war in Iraq, which was already in the planning stages in the 1970s and which would give them control of the world oil supply and therefore the world.

Where do they come up with this stuff? This is obviously not true since the world is actually controlled by aliens from their underground laboratory at Area 51. Everybody knows that. Although it is possible that John Lennon is actually alive and an operative working out of Area 51. I mean, we know Elvis is there.

Oops. Sorry to get off track. Back to the subject at hand.

What elements do art, music and writing have in common? Maybe:
Climax
Contrast
Dissonance
Harmony
Repetition (without monotony)
Rhythm
Surprise

Agree or disagree?
