Prankster altered a thrift store puzzle, then returned it

This "small, harmless long-term prank" is rather brilliant! YouTuber Logan Ivey bought a 100-piece thrift store puzzle of a duck and solved it. He then "customized" it, put it back in its box and returned it back to Goodwill for someone to find in the future. Happy Erster!
