Chocolate on the ceiling? Yep. . We add unsweetened cocoa to the shakes for flavor and because of the antioxidants in the cocoa. We apparently don't look up often enough. We did the 5 year cleaning of the minibar refrigerator. I was laying on the floor to reach the floor of the refer. Laying there I noticed little spots of what turned out to be cocoa on the ceiling. We apparently have a really good blender.
