Answer to #26: He lost $5. The lady from the flower shop gave him $20 in change, but eventually got $20 back. She broke even. The man who got the haircut gave the barber nothing (except counterfeit money) but got $5 back from the barber. So the barber lost only $5, and gave a free haircut.

Riddle: A criminal is brought into a prison for major crimes. The warden informs him that he will be shot in the middle of the prison by 20 of his men. The prisoner is fine with that but he asks for some conditions "All of your men must stand 20 feet away from me and I must be able to select where each of them stands. If I survive, I get to leave."

The warden thinks about it and knows that all of his men will still have an open shot at the criminal, so he agrees.

The next day immediately after the firing squad is positioned the criminal walks out untouched. How did he do it? [Slide for answer]
