One day, Jesus happens across a crowd about to stone an adulteress.
He was shocked at the cruelty, and he opens his arms wide and yells "STOP!!!" in his booming, godly voice. Everybody pauses and turns, stones in their hands, and Jesus begins to preach.
He preaches about brotherly love, and turning the other cheek. His words are inspiring and the crowd grows ashamed as the stones drop from their hands. Finally he ends his sermon, with the words
"Let the one without sin cast the first stone!"
There is a solemn silence, as each person humbly considers Jesus' words in their hearts - until a little old lady in the back picks up a stone and hurls it at the harlot! Immediately, the entire crowd picks up their stones and resumes their earlier behavior.
Jesus, in anger, turns to the little old lady and says,
"Mom, sometimes you really **** Me off!"
