"Sometimes I sits and thinks, and sometimes I just sits...” — A. A. Milne
In an elementary school I was working in many years ago, there was a poster of a Chimpanzee in deep thought with this caption in one of the classrooms. Been one of my favorites ever since. Some elementary school teachers have quite a sense of humor.
