Those of you familiar with Disneyland (or other Disney theme parks) are already familiar with "hidden Mickeys" - three-circle mouse-face icons that can be found if you look for them at the parks.
A couple of weeks ago, I made chocolate chip cookies. After lunch, each of the boys got 4 cookies. Mikey ate one, then paused. He looked at the three remaining cookies on his plate, and arranged them in the iconic Mikey shape.
"Hidden Mikey," he announced, them proceeded to finish off his cookies.
