A whimmy-diddle, also known as the Gee-Haw Whimmy-Diddle ("gee" and "haw" are the commands shouted to oxen on a farm), is a toy made out of a stick of mountain laurel that was traditionally made by mountain parents for their children. Notches are cut down the stick and a propeller is put at the end. When another stick is rubbed against the notches exactly right, the propeller spins. With a lot of practice, the user is able to make the propeller go right or left as desired.
