Santa

I am having a yearly debate about ,Santa, Is he real? So seeing it's the first of December the debate began. My friend gave this story, Well how come at Christmas my family got a piano. And the piano couldn't fit in the elevator. Then we asked him about the chimney.  He said that it was a myth and he came through the wall, Then then we asked how the piano got in and he said that santa used magic and the piano came in. Then he made the mistake of saying that he moved house and he took it apart.
