It's funny but I think what he's pointing out is that it's pretty easy to write a funny parody of a straw man argument.
I read a very good parody of Atlas a while ago. It didn't take words from Rand and mash them up (like this does) - it does a good job of emulating her style while criticizing her ideas. This one's less clever than that, which is a shame.
The man nodded. His nod seemed to reject the possibility of objective thought.
I also like this one, even though it's not nearly as good. http://www.spudworks.com/article/66/2/
