Practised in hilltop yeshivas for almost four thousand years, Jew Jitsu is like krav maga. Only funnier.
UPDATE – I’ve discovered that a mate of a mate, although not the performer above, is an Orthodox Jew who’s also a Kung Fu master called Nick Sporek. There are quite a few people whom I’d wish to lock in a room with half a dozen members of the Golani Brigade. Or one Nick Sporek.
UPDATE2 – The performer in the first video is Yehoshua Sofer, grand master of the Biblical martial art Abir.
