A carburetor walks into a bar…

A priest, a minister and a rabbi are in a bar debating when life begins. The priest says life begins at conception and the minister argues that life begins when their is a heartbeat. The rabbi just sits there drinking his Temple wine. The priest and the minister are getting nowhere in their debate and finally ask the rabbi about the Jewish position on when life begins. The rabbi looks up and says,
"Life truly begins when the last child leaves the home and the dog dies."
