20 or so years ago, bowling in a TNBA in Detroit, made it into the stepladder finals, won my first match, set to bowl Arnie Goldman (he's lefty, I'm righty) in the semifinal match and he spent his entire practice time throwing his plastic ball at the 3 pin. He didn't get enough shots to make a difference but I'm guessing he was trying to play mind games, kind of a dick move but I just laughed at him. He ended up beating me anyways but it wasn't because of that. Had he had 10 straight minutes of doing this, it would have mattered.
