My husband hired a guy to whack down a dead tree in our yard. He told me he might come while we're at work.
I said, "Honey, how can he cut down a tree when no one is home to let him in to use the electricity?"
My husband said, "What does he need electricity for?"
I said, "Where is he doing to plug in his chain sa---oh, shit, never mind."
Mr. G goes, "Honey, how many horror films have you seen where the guy is going to chainsaw someone and he's dragging an extension cord behind him? There's a reason for that."
Ok, granted, not many BUT it would make a great plot twist if the cord yanked out of the wall right as he was getting ready to slice and dice!
