Another brief installment of jiu-jitsu humor from the Washington Post, 1-24-1905.

 An Experiment in Jiu Jitsu.

From the St. Louis Globe-Democrat.
When a footpad approaches you, seze him by the center of the arm and press your thumb violently against a nerve in the inner elbow joint. The footpad will then probably shoot five bulletholes in you while he shrieks with pain. This is jiu jitsu.
