Arthur struggles to understand this, and Ford sees a sofa which he realises is the disturbance. They chase it down, and arrive at Lord's Cricket Ground, two million years later.

Zaphod Beeblebrox and Trillian are on the Heart of Gold. Zaphod is very hung over and refuses to leave the bathroom, even when Trillian attempts to tempt him out with a candlelit supper. Trillian is telling him that the events of the Secondary Phase were all just a pyschotic episode.

Marvin is stuck in a swamp on Sqornshellous Zeta, talking to a mattress called Zem. He is stuck walking in tiny circles because one of his legs has been replaced with a simple metal stick, which cannot bend.
