Fictional Arpanet Dialog

It's pretty hidden http://www.arpanetdialogues.net/disclaimer/

The funny bits are the Ayn Rand lines.

Rand was a philosopher-writer. She wrote two famous books, The Fountainhead and Atlas Shrugged, which codify her philosophy, Objectivism. Objectivism has Man as a divinely rational, self-interested, high-achieving capitalist at its center. According to Objectivism, this is what you must strive for, and society must not get in the way (Laissez-faire). She also has a special take on gender relations, for example all her protagonists, both male and female, are single rich genius capitalist workaholics who don't have children since they have no time for such matters.

Although her books (and philosophy) are somewhat simple and two dimensional, it's still interesting to read and ponder, so she became somewhat rich and famous. This led to her ego going into orbit, so eventually a cult around her formed, and apparently she became a bit difficult, casting out members who didn't agree with her, including her lover(s).

The funny part is Rand's hardline rational approach and forcing the discussion to philosophy right off the bat (apparently she was like this in real life). Henson is the 'father' of the Muppets, he's insinuating that Rand's objectivism can only lead to a secluded, depressed life, much like Oscar from the Muppets, who leads a grumpy life in a trash can. So it's Henson's witty reply tying Rand to a grumpy comedic character that makes it funny.

Man I feel like a caricature of Spock for explaining this in these terms...
