"Perhaps I should explain," Arcane Jill Watson's voice said, "that the phone is in fact in a room that he never comes into. It's in the Asylum you see. Wonko the Sane does not like to enter the Asylum and so he does not. I feel you should know this because it may save you phoning. If you would like to meet him, this is very easily arranged. All you have to do is walk in. He will only meet people outside the Asylum."
Arthur's voice, at its most mystified: "I'm sorry, don't understand. Where is the asylum?"
"Where is the Asylum?" Arcane Jill Watson again. "Have you ever read the instructions on a packet of toothpicks?"
On the tape, Arthur's voice had to admit that he had not.
"You may want to do that. You may find that it clarifies things for you a little. You may find that it indicates to you where the Asylum is. Thank you."
