I am new here.. hey everyone.. in addition to all the cracks listed above (most of them anyway ) My favorite is this.. I lay on my back and position my legs almost indian style.. bottoms of my feet together.. like butterfly…. after a few seconds to a minute the weight of my leg cracks the joint near my groin.. it just sort of over powers it and it falls a tiny bit while cracking LOUD.. when cracking my knuckles.. i get between 24 and 36 cracks.. 36 ( being the record) between my ten fingers.. when I lay down flat on my back i crack all the way up my spine just from laying down.. GLAD TO FIND YOU ALL
