What Would You Do?

Using hidden cameras, host John Quiñones observes and comments on how ordinary people behave when they are confronted with dilemmas that require them either to take action or to walk by and mind their own business. Various scenarios are created that force people to make split-second -- and often surprising -- decisions, and variations of the situation (such as changing the genders, races or clothing of the people involved) are often featured to see if different reactions are elicited. Examples of situations on the show include a waitress being harassed by her boss, and a drunken valet trying to park cars.
