Today's Lunchtime Quiz at mental_floss deals with the TV show CSI (Crime Scene Investigation). You'll be presented with 14 guest stars. Do they play: 1) a suspect, 2) the killer, 3) the deceased, 4) a law enforcement member, or 5) they never even appeared on the show. Although I've seen CSI, it's been years ago, so I scored 29%. You will do better! Link
