Homer becomes a conceptual artist, creating striking "outsider art" that catches the eye of Astrid Weller, a beautiful Springfield art dealer. Astrid arranges for Homer to have his own show, but when the Springfield elite gather for the opening, many are disappointed by his work. Homer decides that he must create something truly groundbreaking, so he floods the entire town, turning Springfield into an American Venice. His piece is a hit and everyone, including artist Jasper Johns, voices their approval.
