Do you know how babies are made?
If not, you're about to learn a lesson you'll never forget.
In 1975, one very daring publisher decided to publish children's book “How A Baby Is Made,” which, as the name implies, details the steps through which a woman gets pregnant, all in a series of creepily graphic illustrations.
How creepy? Like, smiling-baby-coming-out-of-vagina creepy.
It's hilarious, but be warned: After this, you'll never be the same again.
