Mike Ruggles, Supernanny Mike Ruggles, Supernanny

9 pm/ET ABC
Although Jo Frost is a tough act to follow, child therapist Mike Ruggles is up to the challenge for this special episode of Supernanny (and not just literally but figuratively, too, since Jo goes to the U.K. at 8 pm/ET). And what a test it is for Ruggles, who helps a California couple deal with three young daughters, the eldest of whom exhibits an unhealthy disrespect for her parents that's in danger of rubbing off on her sisters. — Joe Friedrich
