Mickey is Everywhere!
The Disney company has a really fun gag going -- hiding Mickey Mouse silhouettes or arranging things in a similar shape (so-called "Hidden Mickeys") on their properties and Websites; in their movies and software. It has become such a phenomenon that people notice the shapes in the strangest places. I found one in Vatican City when I was looking at a satellite image of the country from Digital Globe. Of course, this was rather serendipitous. If you are going to Disneyland soon, look for the 50 that have been placed for the park's birthday celebration.
I help the gag whenever I can. The last few times I did faux finishing on walls in other people's houses I would sneak in a Mickey silhouette or two. They are usually at kid-height, of course.
