9:01-10:00 p.m., ET: "Extreme Parenting"

In an era when people obsess over their children and the topic of how to raise kids has become an area of daily debate, meet some parents who are taking things to the extreme: five dwarf children being raised by a couple who are little people themselves and who insist on teaching the kids how to maneuver in an "average" size house so that they can be prepared for the real world; the father who became an internet sensation when he'd had enough of his daughter's rude rants on YouTube and decided to teach her a lesson she wouldn't forget by shooting her laptop and posting the video on the Internet; the oldest mother in the U.S. to give birth to twins. And how about parents who use bribery - sometimes as extreme as trips to the Grammys - to persuade kids to get good grades? Anchored by Barbara Walters, with reports from Walters, Elizabeth Vargas, Sharon Alfonsi and Cameron Mathison, "Extreme Parenting" delves into wacky, unconventional and sometimes controversial parenting methods. (OAD: 5/4/12)

10:00-11:00 p.m., ET: "Revenge for Real: The Governor's Son"

She ruined his political life� he then ended her life. So goes the tragic tale of Steve Nunn, son of fabled Kentucky Governor Louie B. Nunn, and Amanda Ross, an ambitious and politically connected fixture in the world of Kentucky society. Chris Cuomo reports on what began as a high-society love story that turned into a vicious cycle of retribution and revenge. (OAD: 3/14/12) B

urdened by the expectations of his larger-than-life father, Nunn was down in the dumps in 2006 after he lost his seat in the Kentucky legislature, his marriage to his wife Tracey Damron ended, and he embarked on a life of substance abuse and sexual shenanigans. But it seemed he had reversed his downward spiral when he met Amanda Ross. The two got engaged, Nunn was appointed to a job with the State Health and Family Services Department, and it looked like he was taking the first steps towards a political comeback. But behind the charity balls and Derby week parties, the relationship was becoming bitter and abusive.
