Hehe, actually what made me bring up the knuckles bit was when I saw the last Lord of the Rings movie, this guy was sitting next to me, and right in the intense quiet scenes... *pop* *pop* *pop*... and he just kept doing it... I wanted to belt him LOL.

If someone just does it once or twice I probably wouldn't think much of it
