ok well the weirdest way i've frigured is driving a car, set the seat so that it is a little too close to the steering wheel not so much that your body is touching but just enough for your gas pedal leg is at an upward angel, so drive for a while on cruise and rest your foot on the brake pedal without pressing it or moving your foot, after a while your knee will start to ache a little from staying in the same position, now move you leg back to the gas pedal and you should hear a crack in your knee. works everytime for me.

:twisted: the name is link (yes from legend of zelda) and i am finding that i can crack more and more joints every day and i love it. i know it sounds weird but it's cool to me to know i can do something that alot of other ppl around me can't, until i found this site i thought that i was like the only one or something but i'm glad to know that there are other's like me. well message me sometime and we'll exchange joint abilities lol.
