Jesus was in the town square as a mob was bringing in an adultress to be stoned. When he realized what was about to happen, he called out in his Son of God voice, "LET HE WHO IS WITHOUT SIN CAST THE FIRST STONE!"
Well, this kind of put a damper on the party; people started looking guilty and dropped their stones.
Suddenly a baseball-sized stone came whistling in from the edge of the crowd, striking the adultress square in the forehead, shattering her skull, and dropping her dead.
Jesus, rising to his toes, looked in the direction of the thrower and called out, "Nice arm, Mom."
