英语寓言故事-The Flea and the Wrestler

A FLEA settled upon the bare foot of a Wrestler and bit him,
causing the man to call loudly upon Hercules for help.
When the
Flea a second time hopped upon his foot, he groaned and said, "O
Hercules! if you will not help me against a Flea, how can I hope
for your assistance against greater antagonists?'
