This electrical wiring blows. The hair dryer doesn't.
Reddit user BackOfTheHearse shared this video with the note, "My sister and her husband remodeled their bathroom and had some problems when it came to the lighting..." Like, oh, all of the different switches only turning on the same one light. And when you plug in the hair dryer, it won't work as a hair dryer... but it can also turn the light on.
My favorite part of this video might actually be the wife. She is having SO much fun. I don't know if it's possible to have an audio-only spirit animal, but if so, I would like mine to be this lady's laughter.
