One day Tiger picked up an almost empty tube of Desitin and said, "Look Mom, its a dancing monkey." He then danced the tube on the top of the counter as if it really was a dancing monkey. After that I would ask him to bring me the tube and he would only understand if I asked for the "monkey." So now it is called "monkey" and is universally understood in this house to mean Desitin.
I guess I will have to call hooligan-type behavior "being a gibbon" or "being a lemur." "Monkey" is out.
