's ratings keep falling on Saturday nights. Last week it scored a paltry 0.4 adults 18-49 , behind game show Bet on Your Baby. Vegas has suffered since moving to Fridays. Last week it earned a 0.8 adults 18-49 rating, and was beaten by a repeat of Kitchen Nightmares. Last night it suffered the indignity of being bumped to Saturday at 8PM so CBS could air a news special. (The network decided to keep the reruns it had scheduled, though everything ended up getting preempted and shuffled in most markets.) So tonight we get a unique battle: versus Vegas. Arguably, Vegas has been doing better, but how many people even know it's airing tonight? There's no question both shows are going to do badly, but which show is going to do worse? Make your prediction.
