Back in the time of the Samurai there was a powerful emperor. This emperor needed a new head Samurai so he sent out a message to one and all that he was searching for one. A year passes and only 3 people show up, a Japanese Samurai, a Chinese Samurai and a Jewish Samurai.
The emperor asks the Japanese Samurai to come in and demonstrate why he should be head Samurai. The Japanese Samurai opens a match box and out pops a little fly. Whoosh goes his sword and the fly drops dead on the ground in 2 pieces. The emperor says, "That is very impressive!"
The emperor then asks the Chinese Samurai to come in and demonstrate. The Chinese Samurai opens a match box and out pops a fly. Whoosh whoosh. The fly drops dead on the ground in 4 pieces. "That is really impressive."
The emperor then has the Jewish Samurai demonstrate why he should be the head Samurai. The Jewish Samurai thinks, if it works for the other two, why not try. Whoooooooossshhh. A gust of wind fills the room, but the fly is still alive and buzzing around.
The emperor says in disappointment, "why is the fly not dead?" The Jewish Samurai replies, "If you look closely, the fly has been circumcised!"
