EXACTLY.

Me: What do you want Santa to bring you for Christmas?

Betty: A fireplace in my bedroom, a kitchen and a diamond ring.

Me: Well, he's sitting right there. Go tell him what you want.

Betty: Will you go tell him for me?

Me: Sure.

(later at home)

Betty: Was that really Santa?

Me (hesitation): Yes.

Betty: No it wasn't. He had on short sleeves under his suit.

Me: Why does that mean he's not Santa?

Betty: People who live in the North Pole DO NOT need short sleeves.
