The 'Harry, You Don't Need to Sell It To Me' meme originates from the 2002 film Spider-Man directed by Sam Raimi. In this scene, Harry Osborn (James Franco) is showing Peter Parker (Tobey Maguire) around his father's luxurious penthouse and begins to talk it up, prompting Peter's iconic response. On the internet, this template is used to convey that the user is already a fan of something or completely agrees with a statement, rendering any further persuasion unnecessary. It became a popular reaction image on social media for situations where someone is 'preaching to the choir.'
