This story actually has a pretty solid premise – someone on a generation ship being launched to a distant star discovers that every human being aboard has a parasite inside it, so they take steps to eliminate the parasites. The punchline is that the parasite is what gives human beings intelligence. It’s pure Twilight Zone material.

However, the presentation doesn’t quite line up with the material. Some of the pages, like this one, have some very interesting graphic elements. On the other hand, the denouement of the story is a naked woman floating through a spaceship working out the O’Henry ending over a series of pages.
