Honey, I left the light on

In our garage, we have three 60W incandescent light bulbs. I have chosen not to change these bulbs out because there is no economic reason to do so, since they are on so rarely and for such short periods, and switching compact fluorescent (or any fluorescent for that matter) is a sure way to promote premature bulb failure.

But one night, those lights did get left on overnight. And sure enough, the time-of-use graph told the tale. Since there's 180W of lighting, leaving it on for 10 hours cost us 30 cents, because we're still paying flat rates until the time of use gets activated! Time to get that motion sensor installed in the garage like we had at our previous house.
