 The opening of Part Two , wherein Smithers realizes that he merely dreamed about shooting Mr. Burns , is a reference to the episode " Blast from the Past " from Dallas , in which the events of the entire eighth season were explained away as being merely a character 's dream . The dream itself , in which Smithers and Burns are undercover detectives on the 1960s Speedway racing circuit , parodied The Mod Squad . Groundskeeper Willie 's interrogation , and particularly his crossing and uncrossing his legs , is a parody of Sharon Stone 's famous interrogation scene in Basic Instinct . The nightclub is called ' Chez Guevara ' , a reference to Communist revolutionary Che Guevara .
