"Mystery!" joke
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.
When Santa's turn came after many attempts by others. Santa's story was of just one sentence which read "Oh god, my wife is going to deliver a child".
Ostensibly amused, the organizers asked the american whether it contained all the four ingredients! American 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? He was the winner for writing the shortest story!
