Cracking all of my fingers i can crack 26 joints on both of my hands one on the thumb three on each finger(the tip the middle then the knuckle) and i do it on both hands btw it does not cause arthritis look it up and by cracking them it makes it easier to crack and i also do this weird thing where I can like sorta pop my jaw and it creeps people out a lot so ya. *edit* i also forgot I can nip stop moving no matter what and if indont I will like literall start having uncontrollable muscle spasms or like my foot will start to shake violently
