Don't take my cookie.

I was trying to get a picture of Dean in his new hat since he wanted to wear it all morning and he looked so silly (and cute, of course). But, he kept sitting and standing so quickly that I couldn't get a good one. Thus, I decided to employ any parent's best weapon ... a threat. "Dean, you need to sit down please, or Mommy will take your cookie away." It worked like a charm. I got the best picture of all when he heard that. The expression of utter disbelief. I mean, what kind of horrible Mommy takes a cookie away on Christmas? Well, I promise, I didn't take his cookie (and I really never would have) but I did get a really good laugh!

Can you guess which picture it was?
P.S. I gave you a hint.
