ON "PRIMETIME: WHAT WOULD YOU DO?," FRIDAY, DECEMBER 3

Would you stop a drunk teen from getting behind the wheel? How about an overzealous parent who berates her child while coaching her? Some cases seem to cry out for action, while others seem to present a choice. "What would YOU do?"

Using hidden cameras, "Primetime: What Would You Do?" establishes everyday scenarios and then captures people's reactions. Whether people are compelled to act or mind their own business, John Qui�ones reports on their split-second and often surprising decision-making process. "Primetime: What Would You Do?" airs FRIDAY, DECEMBER 3 (9:00-10:00 p.m., ET) on ABC.

This week's scenarios include:

· Teen Drunk Driving: A tipsy teenager stumbles toward his car in full view of shoppers and diners in a popular shopping area. Will anyone stop him from climbing behind the wheel and driving away? How will people respond when the intoxicated teen is a girl? And what happens if it's a couple on a date - will anyone dare to step in when the boyfriend is drunk and the girlfriend can't stop him?

· Homophobic Parent: A teenage boy tells his father he is gay in the middle of a busy caf� in suburban New Jersey. The father is initially in a state of disbelief and tells his son it's a fad that he will outgrow. The son protests as the father gets angrier and angrier - finally erupting, "No son of mine is gay." The teen dissolves into tears as the father storms out of the caf�. How will bystanders respond? And how will people respond when a teen comes out to an intolerant mother instead?

· Mom's Tirade During Daughter's Ice Skating Lesson: A mom stands rink-side at her daughter's skating practice and yells insults at her across the ice... "That is pathetic!" "You're not a champion! Try harder! Skate faster!" When the daughter comes off the ice, the mom continues her tirade - "This is embarrassing." Bystanders watch as the daughter (actually a real-life skating champ) glides and spins perfectly - will they confront the mother or walk away? Will people respond differently if it's a coach who berates the skater?

"Primetime: What Would You Do?" has won awards from the Chicago International Television Festival, as well as the Avon Foundation's 2006 Voice of Change Award for exposing "injustice and wrongdoing against women and bringing the message of domestic violence to the mainstream." The Columbia Journalism Review has called the program "a Candid Camera of Ethics." David Sloan and Chris Whipple are co-executive producers, and Danielle Baum Rossen is the senior producer.
