The Scandalous Life Inside Appliances

So this video has been trending on the internet this week, and for some reason I am fascinated by it. I shouldn't be. I shouldn't feel like I need to sit through the whole video to see the climax, I mean ending... but I do. Who knew an appliance to make things so clean can be so... dirty.

It raised the question- what else happens behind closed doors with our kitchen appliances? Maybe nothing else is fascinating. But I think a garbage disposal or ice maker could be interesting.

What other appliances could expose a scandalous view?
