Hallmark Holiday VII

Of cert not of the consequence thereof.
You won't hear that one from the mouth of preachers,
when talking about marriage, about love,
or risk a startled snicker from the bleachers.
Since love is an invention of the mind,
a pirouetting egret serves its purpose,
so long as he's the procreating kind,
but so does any bird, so why the circus?

than merely the survival of the fittest?
A salmon swims upstream to chase his shoal,
but surely of a mind to prove the neatest,
the bestest, fastest salmon he can be.
Still hopes to find his soulmate in the sea.
