An ordinary frog met  a toad once, big and brown with spots. 

A girlish older woman, lets say coquettish, stumbled upon the pond.

The toad sang his croak and the frog leaped.

"Ah!"exclaimed the older coquettish woman. 

The toad thought this meant "encore!".

And he sang and sang and sang his croak all the while the frog lept.

it is then that the lady saw the leaping frog.

She laughed: he was so agile!

Leap, leap, leap

The lady took the frog home.

But not before, exclaiming at the toad again:

'encore' as he heard.
