UPDATE: 580,000 reasons to pay attention to Imperva
The episode of "Million Dollar Money Drop" is available here. The question mentioning Imperva is in episode 2. The Imperva question appears at the 34 minute mark (you will be subjected to unavoidable commercials).
The contestants were asked what is the most common password. At this point, they had $580,000 to bet. They put all their money—the full $580,000—on “password” instead of “123456”. Ouch.
