Both my sons discovered their fists when they were about 2 weeks old. They would stare at their fists captivated by its presence.
When Son #1 discovered his fist, my husband and I joked that he was exploring his hippie roots and getting ready to revolutionize the world. Everytime he raised his fist to examine it, we would say. "Viva la raza! Power to the people! Make love not war! Give peace a chance. The fist!"
After Son #2 discovered his fist, we tried saying the same line. Son #2 would not have any of it. He fussed and cried. We immediately changed his saying to "Nacho Macho Muchacho!"
