When Queen Latifah goes to the bank to empty all of her accounts, the bank teller says "and I hope you have a good reason for draining all if these accounts"(or something like that), and Queen says "Yeah, i'm just gonna blow it", at this point, she begins to play with the stack of money

Look at the money closely as she is playing with it, at one point, she will have the bottom of the stack facing the camera so you can see the back of the bills, but wait a minute, there is no back, it's just white blank paper, there is no money after all, just bill shaped printer paper

Now of course they wouldn't use real $100 bills or up on a set, but they could use real $1 bills, they could also run the paper through a printer and at least print something on them, obviously we weren't supposed to see the bottom
