Normal joint: Some individuals have joints that "crack" and is usually an inherited trait. It is usually a normal and benign condition that results from Nitrogen dissoved in the joint fluid (called synovial fluid) suddenly escaping with pressure developing within the joint with normal motion. With rapid escape of Nitrogen, you can hear a popping or cracking sound.
