Hanging objects from a man's balls...

It has been awhile but I seen a man hang two gallon cans of paint from his balls. I would think that would hurt but he seemed to just stand there and do as he was told. I always wondered what other objects have guys hung from that area. Does it hurt or does it feel good.

I had a dom TS in michigan hang about 15 lbs on mine. Doesn't hurt right away. The ache comes after a bit. and grows. Not sure what a max would be. Haven't I seen someone drag a truck with a rope going inside his shorts?
