We're a New Age Thermo Couple

Know what a thermocouple is? If you do maybe you've felt my pain. I wandered around Home Depot today looking for one. They're only $10, but it's necessary to keep a gas furnace on. Did I mention that it was cold last night? I must have burned 20 logs keeping the fireplace at full blast to keep the house warm. As of 15 minutes ago, and me installing the new thermocouple, the furnace is on and working, so all is good. The 50 year old furnace is on it's last legs. Lindsay and I are a new age thermo couple.
