This old digital optical trainer was used on the Three Stooges movie sets. For best effect, the eye poke needed to fall as closely as possible to the center of the eye orbits. The left and right plates were adjusted to approximate the outside edges of the eyes, while the center post was raised or lowered to the length of the nose. The Stooges could then practice quickly jabbing their fingers into the resulting spaces without actually contacting the device. The resulting pokes proved much more entertaining than the previously unrehearsed pokes and the device was soon found on the set of every Stooges short and feature film.......
