In case you haven't heard this one:
In the day of our beloved Lord Jesus, there stood a prostitute surrounded by the townspeople who were about to stone her.
The Lord Jesus says, "If any one of you is without sin, let him be the first to throw a stone at her."
Over the heads of the townsfolk a large stone flies, hitting the prostitute in the head causing her to fall to the ground.
Jesus turns to find the perpetrator, "MOM!!"
