I got in trouble once with that. My dad raised a big stink about my leaving a desk lamp on while we ate dinner. It was a 40 watt bulb, and I left it on for an hour. I was feeling kind of resentful that day--I was usually pretty mellow--and I decided to calculate how much money I had cost the family based on $ per kwh. That light consumed 0.04 kwh while I left it on. I looked at the last electric bill: we paid 2.5 cents per kwh. So later that evening, I handed my dad a penny, and deadpanned, "Keep the change." He looked dumbfounded, then he realized what I was talking about, and he cracked up. You see, he was an electrician, and I was a really mathy little kid, so he got a kick out of my realizing that I had just wasted one-tenth of a cent.
So I bet your dad overcharged you :)
