THE FROG AND THE OX 
An ox, grazing in a swampy meadow, chanced to set his foot among a parcel of young frogs, and crushed nearly the whole brood to death.
One that escaped ran off to his mother with the dreadful news. "O mother," said he, "it was a beast such a big four-footed beast, that did it!" "Big?" quoth the old frog, "How big? was it as big" and she puffed herself out "as big as this?" "Oh, a great deal bigger than that." "Well, was it so big?" and she swelled herself out yet more.
"Indeed, mother, but it was; and if you were to burst yourself, you would never reach half its size." The old frog made one more trial, determined to be as big as the ox, and burst herself, indeed.
