That's pretty cool but here is 2 posts I found on another forum showing that same picture:
POST 1
There was only $500 of real currency, the rest is fake. A security guard was present for the duration of the promotion. People were told they could only use their feet and would not get to keep the money if they were successful.

Actually, the bills on the top are real...underneath they are fake. This PR stunt/promo was done not to far from where I live. What was entertaining was the guy they filmed on the news who took a 30 ft run at it and kicked it as hard as he could. His eyes watered up and he said something like "wow, is that tough". The producer figures he had to have broken every toe on his foot.
The PR company that staged this deserves and award. This promo got international attention.
