I myself have witnessed the "miracle" of childbirth -- during Adult Living class my senior year in high school, 1982. It was a grainy, black and white 5 minute public-service clip put out by some random Eastern Bloc country, probably Romania, produced in the early '50s on 8mm film.
There was no plot, subtext, or context. Rather, it opened with a money shot of a very hairy woman, spread-eagled in stirrups, screaming and writhing uncontrollably, as a couple of Mengele-esque "doctors" in white coats kneeled in front, one holding a rusty dishpan below what I think was her vagina (hard to tell with all that hair obstructing the view) while the other held his hands quarterback fashion screaming TOLJA NAGYON JO!!! TOLJA NAGYON JO!!! as a slimy, blue-grey orb slowly oozed out of a forest.
It left me so scarred I immediately swore off chicks forever. Until, that is, an hour later during basketball practice when I stood mesmerized watching Cindy Jo McIntosh's hooters wage war with each other under her shirt as the cheerleaders practiced their routine.
