A very Christian woman marries a very Christian man. Following the words of the Bible, "Be fruitful and multiply," they have many children. 16 over the course of 18 years, to be exact.
A few years later, the husband dies suddenly of a heart attack. The lady remarries another man, and they have 17 children over the course of 22 years. The woman's second husband dies of old age.
The woman herself dies a few years later. At her funeral, her sister remarks, "Well, at least they're finally together."
"Who? She and her husbands?" asks the pastor.
"No," says the sister. "Her legs."
