Here is a good one.
We went to the cabin (Northern Minnesota) after having been away for a few weeks. We shut off the bedrooms so they are not heated while away.
It had been extremely (-40*F) cold during the week. My son went into the bedroom, looked at the therm. in there and it read -7*F. The outside temp. was -3*F.
He said: "Hey dad, should I open the windows and let some warmer air in?"
