Heinlein also claimed the book its “swiftian in intent” its just done dry. And probably wouldnt have been adapted well to tv.

That being said in the book it was clear carmencita was way out of jhonys league and he was very aware of that. While other heinlenian heroes are generally horny.

Another difference from the heinlenian hero is that jhony is not very smart. He lacks agency and any positive agenda. He just stumbles around.
