Pocket lover

Maddox has found lately that he loves his pockets. It is amazing what he can fit in there. We are having to check them before we go anywhere and before we leave anywhere. He prefers to stuff as many of his cars in there as possible, but this time we were a little surprised what we found. We went to a restaurant over the weekend with family and we left in such a hurry, I forgot to do the pocket check. All of the sudden while were eating, he decided to pull out his treasures. This is what we found.
AA battery and a heart shaped eraser. I would love to know what this boy was thinking when he decided that he needed to take these with him. He cracks me up!
