Santa in a competition

Santa happened to participate in a competition, which was about writing the
shortest story. The organizers had put a condition that a story must have
four ingredients viz. religion, sex, suspense and mystery. Santa’s turn came
after many attempts by others. Santa gave a story, which was just one
sentence and read: “Oh God, my wife is going to deliver a child”. Ostensibly
amused, the organizers asked Santa whether it contained all the four
ingredients! Santa replied affirmatively and gave his explanation as below:

Oh God: religion; my wife: sex; going to deliver a child: suspense (whether
a girl or a boy); “Okay…but where is the mystery?” asked one of the
organizers.

Santa replied, “Who is the father?

Santa was declared the winner for writing the shortest story!
