Welp... Now I've done it.

I crack my neck, my fingers, my shoulders, my toes, my elbows, my back, my ankles, sometimes even my wrists…

Now I’ve done it. I can crack my knees.
My k n e e s.

@513 My knees crack a lot when I get up in the morning - the Nitrogen build-up on joints can be dramatic. Even when I sit down for a bit and get back up, they crack, but it doesn’t hurt ^^
My best friend from middle school had knees that would crack so much that, whenever he got up, it’d sound like a plastic water bottle getting crushed - it was that noticeable, haha!
It wasn’t a defect or anything, didn’t hurt, but I think he just tended to have very loud joint cracks.
We used to laugh every time when he’d show us :)

Shazz_ Even if you’ve never cracked your knees before, they don’t even hurt like fingers would the first few times, or even after that

@513 Yeah, that’s true. I frequently have to crack my fingers prior to performing on piano - without doing that, they can become stiff otherwise.

When I manage to crack every finger on both my hands within 8.5 seconds it causes me extreme joy

I can crack my tailbone.
