"Once upon a time, a perfect man and..." joke

Once upon a time, a perfect man and a perfect woman met. After a
perfect courtship, they had a perfect wedding. Their life together was, of
course, perfect.
One snowy, stormy Christmas Eve, this perfect couple was driving their
perfect car (a Grand Caravan) along a winding road, when they noticed
someone at the side of the road in distress. Being the perfect couple, they
stopped to help.
There stood Santa Claus with a huge bundle of toys. Not wanting to
disappoint any children on the eve of Christmas, the perfect couple loaded
Santa and his toys into their vehicle. Soon they were driving along
delivering the toys.
Unfortunately, the driving conditions deteriorated and the perfect couple
and Santa Claus had an accident. Only one of them survived the
accident.
Who was the survivor?
The perfect woman. She's the only one who really existed in the first
place. Everyone knows there is no Santa Claus and there is no such
thing as a perfect man.
Women, end here. Men, keep going.
So, if there is no perfect man and no Santa Claus, the perfect woman must
have been driving. This explains why there was a car accident.
