This is a famous puzzle from the 1920’s. Once the stick and string are placed in a button hole, it seems impossible to get off! Can be quite mystifying and fun. If you have ever heard the expression “you’ve been buttonholed”, it came from this puzzle! It was first used by an insurance salesman to get a customer’s attention. A large plastic needle with a thread loop fixed to one end is looped through the buttonhole of a spectator's shirt or jacket. He is asked to take it off but he can not do so. The more he tries, the more complicated it becomes. But you can take it off at will. Fun for friends and enemies alike!
