Or we can just act like adults and leave the default caveman pic.
Adults wouldn't be picking on poor, undeserving cave men like that. After all, cavemen were industrious: they invented fire, agriculture and the wheel.
It's insulting to our cavemen and cavewomen ancestors to have their caricatures become synonymous with a weak, lazy, shiftless, aromatically unappealing offshoot of their proud genetic line; an offshoot, that if only we "modern humans" would just get the **** out of the way and let them, Darwin and natural selection would quickly filter out of the damned gene pool.
