How to construct a mugger roll. You buy a golfers wallet and a rubber band. Take a bunch of ones and rubber band them in your golfers wallet.... you use that type of bi fold because it shows off bills in a way that normal wallets don't. I have a friend that made a xerox roll with a few thousand in $100's that he rubber bands together inside of a real $100. Seems to me that might not work in the light of day but whatever. When you're confronted give it up easy but act upset, "That's all the money have in the world *******!" Something like that.
