Painting Rainbows Puns

As a treasure hunter, I had just gotten my hands on a treasure map that lead to the end of a rainbow when a small Irish man approached me. His limbs were being eaten by a flesh eating bacteria. Naturally I felt bad and asked him if there was anything I could do. He told me that he had a famous Van Gogh painting that he’d trade me for the treasure map. Seeing that the painting was worth far more, I obliged, thinking I had just gotten a steal. However, while I was walking home I noticed the man had signed it on the back. The little man had drawn the picture himself, and I had been duped. Let this be a lesson to all of you fellow treasure hunters- never trust a Leper-Con-Artist.
