So, my brother decided to play LoZ - Ocarina of Time again; he’s kind of a douche.
Calm down there, Navi.
What if none of us were alone in fetus stage…
What if there were little trainer-gnomes in there, forcing us to work out because it gets them off; then, when we were built up, we were free to exit the womb?
What if some babies get out sooner because the mother drank a Redbull, and the baby was given the energy to boost its bench-pressing?
What if, when the gnomes were sufficiently pleased with our muscles, they morphed into our bodies; their penises would still continue to get hard when we work out, however, therefore we have abs when we get jacked!
The conclusion being: abs are just rows of horny gnome’s penises.
