This is prompted by an experience I had this weekend. I was spotting Mrs. on the bench. The bench is right next to the preacher curl thing. This African dude asked me, in broken English, for "help." So, thinking he needs a spot, I walk over. He asked me to put one hand on his shoulder and the other on his chin and push back while he twists his head So I'm thinking maybe he has a crick or something...then he asks me to do the other side.
