Cracking the code

Here's the conversation I just had with Jonah:

J: Mommy, can I ask you a question?

Me: Sure.

J: Do you promise to answer it with dignity and respect?

Me: (Laughing) Uh, I'll try.

J: Do you promise to answer it truthfully?

Me: (Wondering where on earth this is going) I'll try.

J: How many numbers are in Santa Claus' phone number?

Me: 10.

J: Hmm. That shouldn't be too hard to crack!
