Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE MOUNTAIN IN LABOUR
A mountain had gone into labour and was groaning terribly. Such rumours excited
great expectations all over the country. In the end, however, the mountain gave
birth to a mouse.
This is a fable written for people who make serious-sounding threats but
who actually accomplish nothing.

in the Aesopic fable tradition. Invaluable.
