The challenge is on

Lorrie's sister Nicole invited her and I down to LA for a big charity fund raiser she organized for the American Indian College Fund. It's one of those black tie affairs with celebrities like Kris Kristofferson, and Benjamin Bratt, with music by R. Carlos Nakai. One of the listed guests is James Cromwell. My guess is that since he was in the movie Babe, barely a week goes by that someone doesn't ask him to say "That'll do, pig. That'll do." So Nicole has challenged me to be the one who walks up to him and try to get him to says his famous line.
So I want to find a novel way to get him to say it. My first thought is to make up a button with my picture on it, and the quote written in the background. So when I walk up to him he feels the need to read it.
Anyone have any other ideas?
