When dangers press, a cunning man
Escapes by any means he can.
A Fox had fall'n into a pit,
And could no way get out of it.
A thirsty Goat hard by who stood,
Cries, "Neighbour is the water good?"
"So excellent," the Fox replied,
"I here remain unsatisfied;
Come down, my friend, take my advice."
Long-beard went down, and in a trice
Reynard climb'd out upon his head,
And left him prisoner in his stead.
