We have a kill-a-watt at home - that's so funny!
I believe DH discovered that there is hardly any electricity that is used when the appliance is turned off. So, unplugging it would only save 1-3 watts.
He said the dryer used the most electricity (although he didn't test the dishwasher or stove/oven). I'm still going to use it though. We lived in a humid climate, and I'd rather use power than have smelly clothes.
(I'm bad, I know.) Our washer is a front-loader and uses very little.
The refrigerator used 200-300 watts when running, but when it wasn't, it used almost nothing. I was excited to hear that! I'm a power nazi when it comes to keeping the fridge door open. It drives me crazy when my 2 yr old tries to squeeze in front of me and hold the freezer door open to grab a popsicle. I'm like "dude! Do you know how much electricity you're wasting!?" Of course, all he cares about is his "pop".
He also noticed that things on standby, like his computer monitor, hardly used anything. Also, he just built a new computer that uses a ton less than his previous one, since he included a much more energy-efficient power supply.
All in all, I can see why you go around and unplug everything. A penny saved is a penny earned, right? I'm too lazy, and like you, my DH would laugh his head off (or get annoyed) if he woke up in the morning and found that I unplugged his computer or the toaster oven.
