The Scorpion's Life Lesson

Let me tell you my story Not that it covers me in glory Looking to be ferried across a river A frog took me on board as long as I stung him never Halfway across we were chatting happily When the temptation to bite his neck came snappily And loth to miss such a chance My fangs plunged him into his death dance Just in time to reach the other side Before his strength ran out and died So my lesson to all with a power to use Never turn up your nose and an opportunity refuse.
