In the town square a nasty crowd had gathered, intending to stone to death a prostitute. From the crowd, Jesus strides forward, holds up his arms and yells "Let ye without sin cast the first stone!"
The crowd is contrite, for none amongst them can honestly say they are without sin. Then a little old, withered up woman comes hobbling up, picks up a good size rock and beans the prostitute right between the eyes.
Jesus just stands there with his hands on his hips and says, "Sometimes, Mother, you really piss me off!"
