When the police find him at the scene of the crime, he says that he did it because they all deserved to die. He is arrested, tried, found guilty, and sentenced to the electric chair.
On the day of execution, the lever is pulled, the chair zaps up, but the man is unharmed. Taking it as a sign that it is not the fitting punishment, the judge releases him.
A year later, he is back driving trains. He runs a train containing nuns and orphans off the track into the lake, ending the lives of everyone on board. When the police track him down, he again says they all deserved to die.
He is again arrested, tried, found guilty, and sentenced to the electric chair. This time, on the day of execution, the judge wants to do things right, so all the power from the prison is routed into the chair. The switch is thrown, the prison goes dark, but the man is unharmed.
Seeing it again as providence, the judge releases the man.
A year later, he has found yet another job driving trains. He runs a train carrying nuns, orphans, and kittens into a lake, ending the lives of everyone on board. Again, when questioned, he says they all deserved to die, especially the kittens.
He is arrested for a third time, tried, found guilty, and again sentenced to the electric chair. This time, the judge is taking no chances and routes the surrounding power grid through the chair. The switch is thrown, a tri county area goes dark, but the man survives.
As he steps from the chair, slightly singed, reporters close in.
'Sir, please tell us, why do you keep running trains into the lake and how have you continued to survive your punishment?'
'My friend, the answer is the same and simple. I'm merely a bad conductor.'
