"The only thing  we  can  do  now,"  said  Benji,  crouching  and
stroking his whiskers in thought, "is to try and fake a question,
invent one that will sound plausible."
"Difficult," said Frankie. He thought. "How about  What's  yellow
and dangerous?"

Benji considered this for a moment.

"No, no good," he said. "Doesn't fit the answer."

They sank into silence for a few seconds.

"Alright," said Benji. "What do you get if you  multiply  six  by
seven?"

"No, no, too  literal,  too  factual,"  said  Frankie,  "wouldn't
sustain the punters' interest."

Again they thought.

Then Frankie said: "Here's a thought. How many roads must  a  man
walk down?"

"Ah," said Benji. "Aha, now that does sound promising!" He rolled
the  phrase  around  a little. "Yes," he said, "that's excellent!
Sounds very  significant  without  actually  tying  you  down  to
meaning  anything  at  all.  How many roads must a man walk down?
Forty-two. Excellent, excellent, that'll fox 'em.  Frankie  baby,
we are made!"

They performed a scampering dance in their excitement.
