As Tuesday's season-finale reveal of Nip/Tuck's Carver draws near, the betting community is wagering on the slasher's identity. According to the Wynn Las Vegas Race & Sports book, Quentin is the current favorite, paying 8-to-5, followed by Matt (5-to-2), Det. McGraw (3-to-1) and Bobolit (8-to-1). Liz, the front-runner per TV Guide's own Damian Holbrook, is Wynn's No. 5 pick, with 10-to-1 odds.
