Answer: Here's what he said in an interview: The thing with him is, you don't know if he's making up a story to get you to do a certain thing or if he's actually giving you a piece of himself. The great thing for me about that particular story is that is what my grandfather did when I was a kid. He actually ran an elevator in a hotel in Chattanooga, Tenn. That was his job. I used to go down there and sit in the elevator with him while he took people up and down. He got tipped that way and had money in his pocket or in a bag - and a little gun. He always had a pistol with him, some brass knuckles. I did not write that, it was just in there. It totally just happened that way. I chuckled about it. I was trying to figure out if I had talked about my grandfather in some interview somewhere years ago or something and somebody read it and put that in there. I never found out if that was the case. I think it's a true story for him.
