"Funny," he intoned funerally, "how just when you think life can't possibly get any worse it suddenly does."
He heaved himself through the door and left Ford and Arthur staring at each other and shrugging their shoulders. From inside they heard Marvin's voice again.
"I suppose you want to see the aliens now," he said. "Do you want me to sit in a corner and rust, or just fall apart where I'm standing?"
"Yeah, just show them in would you Marvin?" came another voice.
Arthur looked at Ford and was astonished to see him laughing.
"What's ...?"
"Shhh," said Ford, "come in."
He stepped through into the bridge.
Arthur followed him in nervously and was astonished to see a man lolling back in a chair with his feet on a control console picking the teeth in his right-hand head with his left hand. The right-hand head seemed to be thoroughly preoccupied with this task, but the left-hand one was grinning a broad, relaxed, nonchalant grin. The number of things that Arthur couldn't believe he was seeing was fairly large. His jaw flapped about at a loose end for a while.
The peculiar man waved a lazy wave at Ford and with an appalling affectation of nonchalance said, "Ford, hi, how are you? Glad you could drop in."
