Ummmm... uhhhhh... Toasters!
That's right toasters are reactionary! Using energy to make your bread crispy, bourgeoise decadence! Really all forms of baking are counter revolutionary, communists should only eat oatmeal!
Okay, fight about it.
Edit: we'll now that enough people have commented, I want to make a snarky edit bemoaning the fact that anyone here would disagree with me. I'm really let down by this community for not validating ever take I have and will probably stop participating here for like two days before resuming posting as much as ever.
I had that idea when I was a kid and put buttered bread into our standard toaster resting on its side. I'm not 100% on what happened. There wasn't a fire but I also didn't keep doing that. Maybe the accumulated crumbs scattered on/next to the heating elements started smoking and I cut the experiment short? Maybe I'll try again with my toaster oven.
