I crack my knuckle all the time.

My hands get stiff and the cracking of knuckles and fingers helps relieve tension.

I crack my knuckles a lot. It feels good. Although sometimes I'll crack too hard, and it hurts...

I click/crack wherever, whenever I feel the urge or that an area feels like it needs to, much to the varied reactions of those around me. My Psychology teacher at college, and my best friend both cannot stand the sounds/sight of people clicking their joints/what have you, whereas my boyfriend is more likely to look over and say 'Ooh.' and proceed to click/crack his hands and neck. :P

I love to crack my knuckles and my wrists. I mess with my mom and act like I'm hitting a tennis ball with a racket every time I do it, can go for a while before it starts to ache. To crack my fingers I just pull them, I can't usually crack my index and thumb but I can on my right hand by making the "talking" motion really hard...don't know when I discovered these but I enjoy it and cracking my knees usually feels great but that only happens when I fall up the steps or something...that happens on average once a week.

I crack my knuckles and wrists all the time... and my neck and back, but I think that has a lot to do with my usual posture. D:

My cuz can crack all her fingers, she just pushes her fingers against her face then takes care of the thumbs.
This guy that sat next to me in high school would twist to each side and crack his back. It was like listening to someone step on bubble wrap but I secretly wished I could do it and freak some people out. ;)

I never crack my knuckles or fingers. I don't know why, but it kind of irks me. Plus I'm afraid that I might dislocate something, even though cracking any part of your body just releases air from your joints.
If anything I crack my shoulders, but even that is an uncommon for me.

arrrgh. NEVAAAH! I hate that sounds with a burning fiery passion! It reminds me of all the times I've broken bones, and therefore I associate it with pain and hospitals and doctors.
I always hit my bf when he does it.. >_> or anyone else for that matter haha

I crack my fingers quite often. It's a bad habit of mine. :P

I crack my knuckles/fingers and toes when I feel that they are feeling... hmm... tired? I don't know how to describe the feeling.

I tend to creep my friends by cracking my knuckles.
It is weird. I tend to wait till all my knuckles are hurting and then I crack them all at the same time. When people see me crack them they are like "uh, Don't hurt me."

I crack my neck a lot, everyday, whenever possible. If I sitting down then I'll crack my ankels. I crack my knuckles every once in a while, same with my back. I hate it when my elbow cracks or my knee, that hurts! My sister calls me "snack crackle pop" because my body cracks so much. I tend to crack my wrist too when my hands are bored.

I crack my knuckles all the time. Especially my right pointer finger knuckle - it helps relieve the pain I have from a couple breaks that led to arthritis-y symptoms. I also crack my elbows and wrists, which freaks a lot of people out. My left elbow cracks nicely when I do it for the first time in the day :P

I crack my knuckles and fingers all the time, once in a while my shoulder will crack on its own. But my back has never cracked before even when I try to crack it.

Yes, sometimes. Cannot do it on purpose. Don't want to either.

Argh, my toes crack all the time. I just have to not move them for like ten minutes and they crack again. It's frustrating. I crack my fingers sometimes, only when I feel pressure. I crack my back a lot but only because there is this one spot I'm always trying to get but can't. My shoulder makes this gross sound since i broke my arm about 16 years ago. My knees pop when I bend down. xD I work at a nursing home and sometimes the old people hear it and a few times I've heard "Damn I thought that was my knees for a second! Then I realized I was sitting down!" xD oh old people <3

I cracked my fingers several times while reading this topic.
I also crack my knuckles, wrists, ankles and toes.
My mom thinks I'm a freak for doing it, but now I'll tell her how many people have the same habit.I myself wouldn't have guessed.
I crack them whenever I get reminded of their existence XP

I don't do it but sometimes when I feel like it I do. Though my sister usually just grabs my hand and does it for me. I just don't do it because it sorta hurts and sting nor do I think about doing it. xD
