Bridget, mareikura, you mentioned once that you enjoyed Last Chance To See. You may be interested in this passage from part of the HHG series:
"We thought," he said, "that you were meant to be telling the
Truth, the Whole Truth and Nothing but the Truth."
"Oh, that," said Prak. "Yeah. I was. I finished. There's not
nearly as much of it as people imagine. Some of it's pretty
funny, though."

He suddenly exploded in about three seconds of manical laughter
and stopped again. he sat there, jiggling his head and knees. He
dragged on his cigarette with a strange half-smile.

"Oh, I can't remember any of it now," said Prak. "I thought of
writing some of it down, but first I couldn't find a pencil, and
then I thought, why bother?"

"None of it?" said Arthur at last. "You can remember none of it?"

"No. Except most of the good bits were about frogs, I remember
that."

Suddenly he was hooting with laughter again and stamping his feet
on the ground.

"You would not believe some of the things about frogs," he
gasped. "Come on let's go and find ourselves a frog. Boy, will I
ever see them in a new light!" He leapt to his feet and did a
tiny little dance. Then he stopped and took a long drag at his
cigarette.

"Let's find a frog I can laugh at," he said simply.


The above came to me as a result of musing on Tweedledum and Tweedledee as possible names for the frogs in question. Thinking of Carroll led to thinking of Adams, hence the passage above. Two interesting characters from The Guide whose names have a nice childish ring when abbreviated are Slarti and Zarni, FWIW.
