Cracking Knuckles

Why do people (including myself) crack their knuckles?
Its not like our knuckles hurt and need to crack them. And the "comfort" we receive after cracking them is nothing noteworthy!
Its a common habit that people have, but why do they start in the first place?
I think it has to do with the same reasons people twiddle their thumbs or absently play with things when distracted. Its just something to do with your hands (ultimately becoming a habit).
Moreover, there may be some element of OCD that a person can't just leave one knuckle cracked without cracking all the rest. I think therefore that this reinforces the habit and adds to the reason why people crack their knuckles.
Or maybe thats the reason for me. What do you think?

On the list of benign bodily functions leading to satisfaction, cracking all 8 nuckles well is way up there.
