This is a really worthless photo but I have shot nothing remotely funny this week so you get it anyway. Like human children, the zoo chimps can get as much fun out of an old cardboard box as out of the toy it once contained. Two were fighting over three boxes. Here one has taken all three boxes and is climbing to a higher level to secure his prizes. It is hard to climb when three of your hands are full. The scene was funny but took only a second to happen and I failed to make a photo that properly covered it.
