Dear Mimsy and Biff,
As you know, I have a magic snowball that lets me look in on children to see if they've been naughty or nice.
I've always enjoyed watching you, because you have always been such good children.
But this year, there must be something wrong with my snowball. Last week, it showed Mimsy pulling the cat's ears, and Biff putting Ex-Lax in Daddy's coffee.
I'm having the Winter Warlock check out my snowball's magic tonight. Then I'll be sure it works right. Then, I'll use it to watch you closely for the next week. I'm sure it will show the good children I've seen all these years.
Won't it?
Love,
Santa
