It's time for the St. Patrick's Day Parade in Springfield and they're giving away free beer! Bart and Milhouse are enjoying themselves at the parade and get their hands on some free green beer. They get totally slopped. They thinks it's time to leave. Still intoxicated they hop in Homer's car. Being 10 and drunk, they are horrible drivers and lose control of the car, driving around the local park. Their adventure and lives end when they run into a telephone pole and the car bursts into flames.
