The Misfit Lovers
They considered themselves outcasts, and rightfully so. Leftfully so, too. For you see, he was a loan wolf, scorned by his brethren and sistren. She was a lone shark, shunned by all other elasmobranch fishes. When they met on the sandbar, it was love at first nip. For you see, they fell into a reverie so smooth that both of them lost consciousness for several decades, and upon awakening, discovered themselves to be a long established happily married couple. Their single offspring, on land and sea, was the most valued product on the planet. For you see, their darling child was work.
