The Doctor enters his TARDIS to discover that Romana redecorated the interior and added a Prime Computer. The Doctor says that he has already seen one on Gallifrey in the constellation of Kasterborous. The sentient computer answers the Doctor's question as to how long his scarf is: "7.013 meters long excluding loose threads." When the Doctor tells the computer "You're going to be all right, kid", an angry message appears on the monitor: "Don't patronise me, Doctor. I'm a Prime Computer."
