On the web the other day, an Atheist posting in a religion forum claimed that Jesus was not crucified through the hands because the Romans didn't perform crucifixions, especially through the hands.
I answered, "Oh, really?" and offered this link:
The Atheist got flustered and answered, "How does this prove the Bible stories were true?"
It proved that the Bible is right and you are wrong about crucifixions, Mr. Atheist.
That's all I needed to do.
