1. When you see a strait wooden stick, such as a broken broom handle, you automatically refer to it as a jo.
I do that!!! In fact, I was at a friends house the other night and her mom told me to help pick up things in the yard.I went out and I saw that my friend was close to a long, straight tree branch and told her "Pick up the jo behind you before you step on it!" She turned around, picked up the stick and glared at me while saying "This is a stick!! Not a jo!!!!" (She is tired of me referring to objects as jo's) I guess I should be a little less Aiki-weapon fanatical around her
