WEDDING GOWN BEHAVIOR LAB.

ROBIN ROBERTS (ABC NEWS) (Off-camera) All right Sam and gang, thanks so much. Tonight, ABC's popular series "What Would You Do" takes on what many feel is one of the most important and emotionally delicate days in a woman's life, her wedding day. But, when it comes to making the bride happy, how far will her friends and family go? Okay, the balance between little itsy bitsy half-truths and brutal honesty is a tricky one, perfect for an undercover behavior lab from John Quinones and his crew. This is going to be good.
