I crack pretty much everything. I crack my neck several times a day. It freaks people out. I also crack my knuckles at both the knuckle and the mini-knuckle at the middle of the finger. Before I go play a gig, I usually spend about 20 minutes cracking my knuckles and stretching my fingers.
I crack my knuckles, but only individually. I can't do that thing where you interlock your fingers and crack all your knuckles at once. I can't crack my neck, and my elbow and knee joints pop on their own.
Knuckles, heaps. Best time is during lectures so everyone can hear it. My ankles crack when I walk down stairs, not so much when I walk upstairs.
Neck occasionally, fingers all the time, back pretty often. I'll crack my toes if I'm bored and have my shoes off. Once in a while something in my pelvic region will crack - that feels really good when it happens - and sometimes my hips will crack.
This thread reminds me how I loved the health insurance I had at my last job in Los Angeles before moving back to Houston. That health insurance covered chiropractic treatments, and I visited the chiropractor every other week to get my back cracked, get heat treatments, and massages. Cost me a $10 copay each time. It was wonderful.
Neck - Constantly Elbows - This one is painful, it seems to get stuck not completely extended, then when straightened it cracks with a sharp pain. Fingers - Ya. Wrists - Yep, especially on the wrist that had a ganglian cyst. Back - Oh ya baby. Ankles - This hurts too. Knees - Only unintentionally walking up the stairs. Toes - Not really Hips - This one feels the best because it seems to relieve a lot of hip flexor tension.
I use a couple of different methods for my back. One way is that I sit in a chair that leans back a little, like an office chair. Lean back in the chair and place your hands behind your head. As you are leaning back, push your hands against your head, so it basically looks like you are trying to push your head/neck up. This cracks the upper part of my back. For the lower part, I usually just stand up and spin my upper body from side to side. As for your hip, unfortunately I don't think that is one that can be taught. I can only pop my hip every few days, and I know when it's time because it will feel a little tight when I walk. To pop it, I stand with my feet about shoulder length apart. Sway your hips to one side, but don't move your feet. This will put pressure on one side of your hip and should crack it. It's a bit painful, but feels oh so good. I don't know how to do the shoulder blades..
I am so freakin' jealous of my wife. She has a way of just twisting her back and all the bones in her low back and hips crack simultaneously. Damn, I wish I could do that. I can't get the chiropractic adjustment on the side because it hurts my back from my back injury, but I love the facing down version and the one for your neck. Ahhhhhh...
As I grew older, I started to crack several of the places mentioned here. I started out just cracking my knuckles, then separate fingers, and so on, until I could now crack those two, my wrists, my neck, my ankles, and my toes. (I think that's it). The only things I don't think I can crack are my back, my elbows, shoulder blades, my knees, and my hip. Maybe I'll be doing those later? I basically just do it to pass time in class. If I finish early, I'll just go through the routine and hope it takes some time. Unfortunately, sometimes I have so much time or not enough time in between these periods. I'll try to crack my neck even though it doesn't need to be, so I end up looking like some guy twisting his neck. One weird thing, or at least I think it is weird, is that I'll sometimes walk around barefoot and my ankles will crack, or pop, or whatever, with every step I take. It wouldn't seem so weird if I took like 10 or 20 steps, but it seems to keep going on. It doesn't happen all the time, so I can't really do it on purpose, but it does happen a lot.
You need to talk to Another Brother. I do believe that he has mastered the art of cracking his azz. Last I heard, he was passing on the art to his children...
Usually I feel some tightness near my shoulderblades. Sit down, very close to a desk. Lean forward over the desk. Put one of your forearms on the desk. Put all of your weight on it, and turn sideways away from it. Usually I feel a bit of resistance as I'm doing this, then KRACK! followed by a "What the hell was that?" That's how I do it.
