Christians: Do you teach your children the story of Santa Claus?

When many of them don't know the full story of Christ? And if so, would you call yourself a liar because you are telling them about a man in a red suit coming down the chimney giving them presents every year? Hypothetically if you died on Christmas morning after telling your child that Santa Claus was real (there was a real Santa Claus...just not the version many of us feed our children), what do you think would happen? Any thoughts?
