There was a competition going on in Spain to see who the world's greatest swordsman was. The final three competitors had been chosen, and were brought on stage in front of the anticipating crowd to showcase their talent. The first swordsman stepped forward causing the crowd to hush. One of the judges proceeded to release a small black fly and let it buzz around the stage. With the flick of his wrist and faster than you can blink the fly hit the ground in two pieces. The audience bursts into applause as the swordsman steps back. Next is the second swordsman's turn and he faces the same challenge. The fly is released and in two swift motions - swish! swish! - he cuts the fly into four pieces. The audience is even more impressed and gives the man a standing ovation. Finally, the third swordsman takes the spotlight and another fly is released onto the stage. The swordsman takes one quick swish at the fly but it continues to fly around the stage. The audience is dumbstruck. Finally someone from the audience speaks up: "Sir...the fly is still alive." "Ah, si," replies the swordsman, "but he will never be a father."
