Cracking your knuckles causes arthritis
A study of 300 people over 50 found no difference in arthritis rates between habitual knuckle-crackers and non-crackers. Dr. Donald Unger famously cracked knuckles on only one hand for 60 years and found no difference between his hands (he won an Ig Nobel Prize for it). The popping sound is just gas bubbles collapsing in joint fluid.
