Unfortunately, the driving conditions deteriorated. The perfect couple and Santa Claus had an accident. Only one of them survived the accident.
Women stop reading here... that is the end of the joke.
By the way, if you're a woman and you're still reading... this illustrates another point: "Women never listen."
Q: If Santa doesn't have to age, then why has he become old?
A: He only appears to be old. He's an undercover kid.
A: If you were being pulled by eight flying reindeer, wouldn't you fly too?
A: They are not equipped with ABS and thus tend to bump into things on slippery surfaces. This is why Santa is often seen with a red nose (the sleigh doesn't have an airbag, either).
Q: Why do we wish people a "Merry Christmas" instead of a "Happy Christmas"?
A: The two are about the same, but with "Merry Christmas" an extra twinkle is seen in the eyes.
Q: Why is a Christmas tree that has been chopped down called a "live Christmas tree?"
A: It's dead but doesn't know it, and yet it's having the time of its life.
Q: How many gifts can Santa Claus's bag hold?
A: One less than infinity. Why one less? Because there's a limit to everything.
A: For the poor, for the joy, and because a bell can say what words can't say.
Q: What can't words say?
A: The moment you wake up on Christmas morning, listen carefully. You may hear then what words can't say.
