Ugh, such a gross misinterpretation. One of Rand's big points is that it doesn't matter what you're doing as long as you do it well. One of her physicists becomes a janitor, and when the misguided protagonist expresses horror at that, he says that there's nothing wrong in doing menial tasks.
Bob is incredibly stupid because he makes fun of something that Rand expressly says is a good thing. Furthermore, the Rearden parody ("I only know how to pay people to invent alloys") ignores that in the book, Rearden is the scientist who invents the alloy himself. He's portrayed as a very skilled mathematician. So it's a good parody IF you're okay with laughing at something that Rand never actually wrote.
