Better Than The Big O

HERE'S a poetic take on the bomb:

Family planning is an alien concept,
We impregnate everything that moves.
Commoners fruit their partner's bellies,
Virile heroes seed the earth's womb.
Make no mistake: size matters and sound matters.
Only the under-endowed would demur.
The big O's good, but
The big bang's better, so wonderfully nuclear.
