The Scenario: But not all proposals end in a happy "I do." Especially when the lady being proposed to is hiding a secret of her own: another lover. What would you do if you witnessed a man about to propose to someone who was obviously being unfaithful? Would you step in and stop him from making a potentially devastating mistake? Our actor plays a nervous boyfriend about to propose to his girlfriend, another actor, who is conflicted by her feelings for a second lover. Our "What Would You Do?" hidden cameras are rolling at Holsten's Confectionery in Bloomfield, N.J. If you knew the bride-to-be was unfaithful, would you interfere?

What They Said:

"It's a big day, I plan on asking her to marry me."

"Hey baby, what's going on? I told you not to call me right now."

-- concerned customer to our baffled boyfriend.

"There's a reason for everything in life. You don't see it now, but you will."
