Hey, and welcome to the short stuff, Josh, Chuck, Jerry, sitting in for Dave.

So this is short stuff.

Chuck, I have a question for you.

Are you cracking your knuckles right now?

Yeah.

That wasn't like a Foley effect?

This is what my knuckles sound like when I crack them.

That's it.

Yeah, I can't do it again because I have to wait 20 to 30 minutes for the air bubbles to come back and cavitate once more.

Yes.

If your bones ground together, you would not be able to think of anything else but your bones grinding together because you would be in so much pain that you would know your bones are grinding together.

That's not what cracking your knuckles is.

It turns out instead it has everything to do with the space in the area around where your bones come together.

Your bones don't actually come together.

Yeah, it's thick.

It tastes just like orange crush, surprisingly.

And when you pop your knuckle, what you're doing is stretching or bending the ligaments and connective tissues and the synovial fluid there too, right?

So when you do that, that capsule is what it's called, the connective tissue capsule that includes the synovial fluid.
