Dr. Phil Metzger:

Wanna hear a weird but true story? (I have a few minutes to type, so here goes). I almost lost my hearing from the lid on the tank of a toilet. Noise-Induced Hearing Loss. You wouldn’t think a toilet lid could be so loud, would you? Well, I learned otherwise…

I was fixing the mechanism inside the tank of the toilet. The only thing left to do was to put the ceramic lid back on the tank. Unfortunately it slipped out of my hands and banged on the ceramic of the toilet rim. Again, you wouldn’t think that would be so loud, would you?

Well, the sound stunned me.

This is the most wondrously nerdy thing I’ve read all day. Thanks to Josh for the Twitter thread.
