Yes, the challenge is to burn a "benjamin." Not out of disdain for the value of $100 bill, but to show that money doesn't mean much. Life is about fun, happiness, and laughter. Money is a means to an end. You want to acquire wealth, but are also willing to let it go, to prevent it from owning you.
I think one burning ceremony is enough to prove the point. If you're a couple, you may burn two bills so each will get the experience. Any takers?
