My brother and I, after much discussion, thought we had figured out how babies were made. Unfortunately, lacking the knowledge of the female anatomy, and of the existence of a second fluid from the penis, we decided that the man put his penis into the woman's anus and urinated. (un)luckily, our mother overheard this and set us straight...somewhat; "you NEVER do that!" *THWACK*
