best of both worlds

you know mr darwin's theory about survival of the fittest?
the one that suggests the genes you inherit
are supposed to be the best ones from either of your parents
well mama thinks it's actually gone haywire in my case
she reckons i've managed to acquire
her late-night-owl gene
coupled with
papa's early-to-rise gene...
so you can imagine what the means for them, hey?!
