What Would You Do?

I don't know how many of you have seen the show "What Would You Do?" but if you haven't, I think it's worth checking out. It's on at 10pm ET on ABC, and the basic idea is that it's a hidden camera show. The great thing about it is that instead of trying to catch embarrassing moments, it's trying to catch people doing the right thing. It has made me stop and think more than any other show I've ever seen in my life.
Another good thing about the show is that it's not all serious. Some of the segments are pretty light. For example: what would you do if your online date was not the person they portrayed on their profile. Then there are some heavier things: what would you do if you saw a store clerk and security guard very obviously harassing someone because of their race? Or if you heard a baby crying, left alone in a hot car?
Granted, even the "light" situations have deeper implications, and your reaction reveals a lot about your character. In many cases, I watch the show and hope that I'd have the courage to say something. Other times, like when they had a group of kids beating up an immigrant, they were looking for people to physically step in. I'll be honest, I'm not going to get in the middle of a fight; I'm not a big person. But I will call 911 and look for help in the immediate area (probably the best part of that segment was when this HUGE guy came running over, and the actors playing the kids beating the guy up literally ran away).
Anyways, this show is my weekly conscience examination. What would I do? I hope it would be the right thing.
