As Mr. Overwater aptly asks, in a comment on a different post, "Why lie?"
My question, specifically, is "Why would Al Gore tell an obvious, easily disconfirmed lie about the number of people who watched his public masturbation on the environment?" Because he did lie, egregiously. The only way you can get to Al's numbers is if you count people who watched for five seconds, and then replicate them so that each five seconds counts as a new viewer, over the whole period. If you don't do that, you get this.
The answer, I'm afraid, is not very complicated. Al Gore has become the Jimmy Swaggart, the Pat Robertson, and the Billy Sunday of the Enviro Movement. Of course, quite a few people in the Enviro movement are too smart to fall for this Al A-Gorey.
"Oh, HELP me, Jeebus! Send money right away, to save the world from global warming! Send money! We accept all major credit cards. And I accept $100,000* per speaking engagement so I can maintain my 20,000** square foot home with gaslight lanterns on the driveway! Carbon offsets for you, massive hypocrisy for me!"

NOTES: *--not an exaggeration. **--an exaggeration, or a "lie" if you will. This whole post is a satire, not a documentary. I don't think Al Gore says "Jeebus;" he says "Gaia," the Earth Mother. Oh, and I should note that Al Gore never claimed to invent the internet. He also didn't invent the religious scam. But he used the internet to make money off his enviro-religion scam very effectively.
