Unfortunately, the driving conditions deteriorated and the perfect couple and Santa Claus had an accident. Only one of them survived the accident. The perfect woman survived. 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 stop reading here.
That is the end of the joke. So, if there is no perfect man and no Santa Claus, the perfect woman must have been driving. And that explains why there was a car accident. A woman goes into Wal-Mart to buy a rod and reel. She doesn't know which one to get so she just grabs one and goes over to the register.
