Snap, Crackle, Pop

No, I am not talking about Rice Krispies. I am talking about something a lot people do. This concerns the art of knuckle popping. Are you one of the humans who have turned this pastime into a fine art? I have found people either do this little activity gleefully or they are filled with horror and their skin crawls when they are in the presence of one who is performing a snap on his knuckles. I personally am one of these people and I am wondering if you are a snap, crackle, pop kind of person?
