My parents used to explain the act of reproduction as when the man combines his "seed" with the woman's "egg". My limited understanding of these terms lead me to the conclusion that a man could take just any old seed like a popcorn seed, mash it together with a chicken egg that a woman was holding, and presto, the woman becomes pregnant!
...Yes, I shame to admit that this was after I understood the concept of pregnancy.
I used to rationalize single mothers in my head by reasoning that the woman could just take her own popcorn seeds.
