The Two Frogs

From The Fables of Æsop:

One hot summer, the lake in which two Frogs lived was completely dried up, and they were obliged to set off in search of water elsewhere. Coming to a deep and deliciously cool well, one of the Frogs proposed that they should jump in at once. "Wait a bit," cried the other; "if that should dry up, how could we get out again?"
