It's explained on the DVD, the problem is that handing out money for examination looks REALLY suspicious and silly. I could se you doing it for friends, but for an actual gig. Just showing the bills on both sides would be the best thing to do, because you don't risk somebody trying to steal your money or anything afterwards.
If you want to learn a relatively simple bill change go ahead and learn, Bob McCallister's $100 Bill Change. You only change one bill, but, neither of the bills you use are gimmicked in anyway, and as soon as you're done your change you can instantly change it back.
