A divorced couple decides to give their marriage another go, with one simple rule: neither ever talks about the romantic liaisons each had while they were apart. That's the premise of UPN's comedy Second Time Around (9:30 p.m.-10 p.m., WUTB, Channel 24), and it doesn't take long to break the rule. First, Jackson (Boris Kodjoe) learns Ryan (Nicole Parker) at one point posed nude for a painting. But lest he get all holier-than-thou, Jackson has a whopper of a secret himself. Can this remarriage be saved?
