I have a horrible knuckle popping problem. If I do it too aggressively my entire right hand is in pain for a few days making it difficult to write, craft, or even start my car. If I don't do it at all my fingers become so stiff and it's difficult to bend them. I know that the popping of the knuckles isn't terribly harmful but it is incredibly annoying to those around me.

My knees also pop like crazy, sometimes with slight movements that are mostly unnoticeable to those around me.

I also have a bad habit of popping my gum. I try not to chew gum in public because popping gum is the most annoying sound in the world. I seem to have become what I once hated.
