Crossed Wires

The basement apartment was freezing and there was no way I could cope. I called the landlord and he came by with a heater.
     “Great," I said, ”now my electricity bill will sky-rocket."
     “It’s okay,” he said, “Plug it into this outlet, here, and you won’t pay a thing.”
     The heater definitely made the place liveable. After I had been living there a for awhile I got to know the other tenants in the house. The woman upstairs from me remarked, “It’s weird, suddenly a couple of months ago my Hydro bill shot up, and I can’t figure out why.”
