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...
