During the French Revolution there were three men about to be beheaded. The first was a priest, the second a banker, and the third was a engineer. The priest was to be executed first. He requested that he be allowed to be beheaded laying on his back so that he could be facing heaven. His request was granted. The guillotine blade fell and stopped just a few inches from the priest's throat. According to the law, because the blade stopped, he was released. Then it was the bankers turn. He thought " If it worked for him it'll work for me!". He did likewise and the blade stopped. He was also released. Then came the engineer's turn. He did likewise. But before the executioner was ready to pull the lever he said "Hey! I think I see what's wrong with this thing! I think I found your problem!"
