This puzzle is designed as a bit of a prank. The wooden peg is threaded through an unsuspecting friend's buttonhole. The person must then remove the puzzle from their shirt. If they can't remove it, then they must walk around all day with a wooden peg hanging from their shirt. Solving it is more difficult than you would think!
