It was a comedy video, where they were making a parody of those people who give away flyers out on the streets. Except in their case, they were giving away free money. However, the interesting thing here was that NOBODY took the money (it could have just been smart editing - but still, a lot of people did not take the money).
The fact that they're giving away free money on the streets (even though they did not have a catch), people will begin to question and perceive the money as being fake, since this is an odd thing to do.
This could be an interesting marketing lesson because it goes to show that just because it's free doesn't mean they'll take it.
If you want to see the video, it's over at my blog (I also go into more details talking about this):
Just Because It’s “FREE” Doesn’t Mean They’ll Take It
