In Isaac Asimov's "The Last Question", there is a passage which reads:
"Sure you are. You're weak on logic, that's the trouble with you. You're like the guy in the story who was caught in a sudden shower and who ran to a grove of trees and got under one. He wasn't worried, you see, because he figured when one tree got wet through, he would just get under another one."
"I get it," said Adell. "Don't shout. When the sun is done, the other stars will be gone, too."
Does anyone know which folk tale/fable is he referring to here?
