Well, you see, it was to avoid being electrocuted. ;( Since Grandma's clothing is non-conductive, standing on it would prevent Faw from getting electrocuted. He wouldn't if the resistance between him and the ground was higher than the resistance through the metal rod. In fact, I know the metal rod is more likely to be a good conductor than Faw but I decided not to risk making Fawburger out of him.

Look at 'gate mechanism'. Try to operate it and open the gate.
