It's Jiffy's job to foil plans when they're plotting to get rid of popular or entertaining players. It's also his job to stir the shit and make people look like idiots. He always tries to get someone say something like "Jeff, I feel secure that I'm not going home tonight because I trust my alliance 100%" right before they get blindsided. Remember when he did that to Chrusty. She went on and on about how she was in the drivers seat and then promptly got her ass booted. Ratings gold!
