"Who Shot Mr. Burns?" is a two-part episode of the American animated television series The Simpsons. Part One is the twenty-fifth and final episode of the sixth season and originally aired on the Fox network in the United States on May 21, 1995, while Part Two is the season premiere of the seventh season and aired on September 17, 1995.Springfield Elementary School strikes oil, but Mr. Burns steals it and at the same time brings misery to many of Springfield's citizens. Part One has a cliffhanger ending where Mr. Burns is shot by an unidentified assailant. In Part Two, Springfield's police try to find the culprit, with their main suspects being Waylon Smithers and Homer Simpson.
Both episodes were written by Bill Oakley and Josh Weinstein; Part One was directed by Jeffrey Lynch and Part Two by Wes Archer. Musician Tito Puente guest stars as himself in both parts. "Who Shot Mr. Burns?" was conceived by series creator Matt Groening and the writing staff decided to turn it into a two-part mystery episode. Part One contains several clues about the identity of the culprit because the writers wanted it to be solvable.
The concept for the two-part episode was the episode of the primetime soap opera Dallas titled "A House Divided", known by most as "Who shot J.R.?" in which character J.R. Ewing was shot. In the months following the airing of Part One, there was much widespread debate among fans of the series as to who actually shot Mr. Burns and in many ways the public reaction and response to the episode mirrored that of its "Who shot J.R.?" inspiration. Over the summer of 1995, Fox offered a related contest which was one of the first such endeavors to tie in elements of television and the Internet.
