While [bad word]  the narrator describes the state of medical science in the universe, with artificially induced injuries.

Meanwhile, Zaphod and Ford have landed on the back of one of the birds from the previous episode, and eventually convince it to reach the ground by wrapping Ford's towel around its eyes.

Lintilla, Arthur and Marvin continue their escape, while Ford and Zaphod finally arrive at a large, very old building, and enter it to take shelter from the still angry bird people.

They discover that the building is a spaceport, and find abandoned ships left inside it. One such ship is still connected to supply lines, and still has power. Zaphod makes himself a stethoscope (for both heads), and holds it to the hull of this ship. He's stunned by what he hears inside, and here the episode ends.
