When does life begin?

A Catholic Priest, a Protestant Minister and a Rabbi are discussing the question of: "When does life begin."

"Without any doubt" says the Priest, "Life begins at the moment of conception, when the sperm meets the egg."

"No, no!" says the Protestant Minister. "Life begins at the moment of birth, when the baby emerges."

"No way," says the Rabbi. "Life begins when the last kid is out of college"
