A form of the martial arts used by the ninjew. Kept secret among the Hebrew people, jew-fu allows the ninjew to perform spectacular feats of dexterity, dominate his opponents, or open an otherwise stubborn beer. Used by ninjews to fight pirates.
Darrin: How the hell did you beat me?
Ted: I'm a ninjew.
Darrin: Oh yeah, I forgot. Pwned by the jew-fu again.
