Time to send the brain on vacation! In a first for the Survivor-lite competition, 13 former couples from The Real World and other MTV shows (hello again, C.T. Tamburello and Diem Brown!) pair up and battle in physical-endurance tests in the Dominican Republic. The games themselves fail to rivet (in one, the teams dip their bodies in a tub of honey and try to scrape off the most goo). No harm, though, in watching sexy singles spar -- and maybe reignite passions -- in paradise. (MTV, 10 p.m.)
