- People who talk to themselves on the phone, - said Ford, - never
learn anything to their advantage.
- But...
- Look, - said Ford. He picked up an imaginary phone and dialled an
imaginary dial.
- Hello? - he said into the imaginary mouthpiece. - Is that Arthur
Dent? Ah, hello, yes. This is Arthur Dent speaking. Don't hang up.
He looked at the imaginary mouthpiece in disappointment.
- He hung up, - he said, shrugged, and put the imaginary phone neatly
back on its imaginary hook.
