The Sundance Kid is buried at the Springfield Cemetery and is a founding member of the A Hole in the Ground Gang. He is a parody of Butch Cassidy and The Sundance Kid's real life gang called A Hole in the Wall Gang.
When Springfield banned all of their guns after Lisa's newfound inspiration, the 'A Hole in the Ground Gang' rises from the dead. They have the only guns left in town and use them to terrorise the citezens of Springfield. They are stopped when Homer travels back in time to stop people recycling their guns. They then shoot the graves of the members of the 'A Hole in the Ground Gang'. Then, Comic Book Guy says "What happen to Butch Cassidy?" The members of the 'A Hole in the Ground Gang' then flee their graves and run-off into the sunset in a halo of gunfire.
