ok this is tricky and takes some practice and a real professional genital magician to pull of. clamping your ball sack with one hand and leaving a little air room. while squeezing you ball sack, make sure you mimic the heartbeat of any individual. give it a few squezzes in a row . if done correctly your ball sack will pulsate through the opening made with yuor hand, thus representing a chicken heart. a.k.a. the gorrilla kidney
