In childbirth class, they showed us actual pictures of a fetus developing inside a uterus. They didn't tell us how these pictures were taken, but I suspect it involved a great deal of drinking. We saw lots of pictures. One evening, we saw a movie of a woman we didn't even know having a baby. I am serious.
Some woman actually let some moviemakers film the whole thing.
She was from California. Another time, the instructor announced, in the tone of voice you might use to tell people that they had just won free trips to the Bahamas, that we were going to see color slides of a Caesarian section. The first slides showed her cheerfully holding a baby. The middle slides showed how they got the baby out of the cheerful woman, but I can't give you a lot of detail here because I had to go out for 15 or 20 drinks of water. She evidently felt this was a selling point.
