I am translating this one from French, so please bear with me…
——————————
Once upon a time, a perfect man and a perfect woman met. After flirting with each other, they got married. Their mariage was, obviously, perfect!

On the night of Christmas, this perfect couple were driving in their perfect car along a desert road, when they noticed someone having problems on the side. Being perfect, they stopped to offer their help. The person needing help was Santa Claus, with his backsac full of gifts.

Since they didn’t want millions of kids throughout the world to be deceived at Christmas, the perfect couple decided to take Santa onboard their perfect car and drive him around to help him distribute all of his gifts. Unfortunately, the perfect couple and Santa had an accident…

Only one of them survived… Who was it?
