I once laid my sneaky Pete cue on the table to rack. My opponent decided that he wanted to try it. He figured it was a bar cue and was laying a claim to it. He was deaf to my explanation that it was My cue. He reinforced his claim by putting a 2 handed death grip on it as we stood toe to toe. So when my cordial explanation was ignored, I reached down below the joint as he tightened both hands above the joint. I gently started to unscrew. If the dispute was elevated to violent means, I would have the Billy club butt and he would be left shafted. 
His look of amazement was priceless. He released before the last thread was cleared. We were able to continue amicably. Shrug
