Counterfeiters

Two counterfeiters were working on making some fake bills starting with $100’s. One of the plates slipped without them noticing, and printed out a whole run of $18 bills. Instead of wasting them, they decided to head south to see if they could pass them off, thinking that locals wouldn’t know a fake bill from a real one. They stopped at a local convenience store to test the theory. As they approached the counter, they asked “Can you make change for an $18?” The response came quick. “How do you want it, two $9s or three $6’s?”
