Three men, one an engineer, are convicted to die by Guilotine. The first is loaded into the device, the blade drops and stops an inch short of the guys neck. Thinking it a sign from God that the man is innocent, the executioner sets him free. Number two is loaded, the blade drops, and the same thing happens. The prisoner is set free, and it's the engineers turn. Down comes the blade only to slam to a halt halfway. The engineer turns his head, looks up at the blade, and says'
"Aha! I see what the problem is..."
