The Ox and the Frog

AN OX drinking at a pool trod on a brood of young frogs and
crushed one of them to death.  The Mother coming up, and missing
one of her sons, inquired of his brothers what had become of him.
"He is dead, dear Mother; for just now a very huge beast with
four great feet came to the pool and crushed him to death with
his cloven heel."  The Frog, puffing herself out, inquired, "if
the beast was as big as that in size."  "Cease, Mother, to puff
yourself out," said her son, "and do not be angry; for you would,
I assure you, sooner burst than successfully imitate the hugeness
of that monster."
