Hand in the Cookie Jar

I don't want to go into too much detail here, but the last time my kids stole cookies I punished them extremely severely. I assure you that they have very unpleasant memories associated with the cookie jar. I was so sure that they would obey, I decided the jar would be the best place to hide my gun. There were at least five in the clip and one in the chamber when I put it in there, and now there are only three in the clip and none in the chamber.

Now I know for sure that they've been stealing cookies, but I'm sure how much further I can go with the punishment without that meddling doctor noticing.
